Example Question #62 : Functions
The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurring between the and the period of the race?
The race car driver is driving at a consistent speed
The race car driver is increasing his speed
The race car driver s decreasing his speed
The race car driver is waiting to begin the race
The race car driver is driving at a consistent speed
The time is displayed along the x-axis of the provided graph. Between the and the period of the race, the driver is going at each time point. We can see from the straight line between those two points that the race car driver's speed doesn't change; thus, the race car driver is driving at a consistent speed.
Example Question #1 : Describe Qualitatively The Functional Relationship Between Two Quantities By Analyzing A Graph: Ccss.Math.Content.8.F.B.5
The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurring during the last of the race?
The race car driver is decreasing his speed

The race car driver is increasing his speed
The race car driver is waiting to begin the race
The race car driver is decreasing his speed
The time is displayed along the x-axis of the provided graph. During the last of the race, the driver goes from , displayed on the y-axis of the graph, to . We can see the line between those two points is decreasing in a negative direction, or getting slower; thus, the race car driver is decreasing his speed.
Example Question #2 : Describe Qualitatively The Functional Relationship Between Two Quantities By Analyzing A Graph: Ccss.Math.Content.8.F.B.5
The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurring in the first of the race?
The race car driver is driving at a consistent speed
The race car driver is waiting to begin the race
The race car driver is increasing his speed
The race car driver is decreasing his speed
The race car driver is increasing his speed
The time is displayed along the x-axis of the provided graph. During the first of the race, the driver goes from , displayed on the y-axis of the graph, to . We can see the line between those two points is increasing in a positive direction, or getting faster; thus, the race car driver is increasing his speed.
Example Question #4 : Describe Qualitatively The Functional Relationship Between Two Quantities By Analyzing A Graph: Ccss.Math.Content.8.F.B.5
The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurring when the time is at
The race car driver is increasing his speed
The race car driver is waiting to begin the race
The race car driver is decreasing his speed
The race car driver is driving at a consistent speed
The race car driver is waiting to begin the race
When the time is at , displayed along the x-axis, we see that the speed, displayed along the y-axis is also . If a car has a speed of , the car is not moving. And if the time is at , the race has not started; thus, the race car driver is waiting to begin the race.

The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurring between the and the period of the race?
The race car driver is decreasing his speed
The race car driver is driving at a consistent speed
The race car driver is waiting to begin the race
The race car driver is increasing his speed
The race car driver is driving at a consistent speed
The time is displayed along the x-axis of the provided graph. Between the and the period of the race, the driver is going at each time point. We can see from the straight line between those two points that the race car driver's speed doesn't change; thus, the race car driver is driving at a consistent speed.
Example Question #7 : Describe Qualitatively The Functional Relationship Between Two Quantities By Analyzing A Graph: Ccss.Math.Content.8.F.B.5
The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurring in the last of the race?
The race car driver is decreasing his speed
The race car driver is waiting to begin the race
The race car driver is driving at a consistent speed
The race car driver is increasing his speed
The race car driver is decreasing his speed
The time is displayed along the x-axis of the provided graph. During the last of the race, the driver goes from , displayed on the y-axis of the graph, to . We can see the line between those two points is decreasing in a negative direction, or getting slower; thus, the race car driver is decreasing his speed.
Example Question #8 : Describe Qualitatively The Functional Relationship Between Two Quantities By Analyzing A Graph: Ccss.Math.Content.8.F.B.5
The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurring when the time is at
The race car driver is waiting to begin the race
The race car driver is decreasing his speed
The race car driver is increasing his speed
The race car driver is driving at a consistent speed
The race car driver is waiting to begin the race
When the time is at , displayed along the x-axis, we see that the speed, displayed along the y-axis is also . If a car has a speed of , the car is not moving. And if the time is at , the race has not started; thus, the race car driver is waiting to begin the race.
Example Question #9 : Describe Qualitatively The Functional Relationship Between Two Quantities By Analyzing A Graph: Ccss.Math.Content.8.F.B.5

The race car driver is increasing his speed
The race car driver is increasing his speed
The time is displayed along the x-axis of the provided graph. During the first of the race, the driver goes from , displayed on the y-axis of the graph, to . We can see the line between those two points is increasing in a positive direction, or getting faster; thus, the race car driver is increasing his speed.
Example Question #10 : Describe Qualitatively The Functional Relationship Between Two Quantities By Analyzing A Graph: Ccss.Math.Content.8.F.B.5
The graph provided displays the speed of a race car during a race.
Based on the graph, what is likely occurred between the and part of the race?
The race car driver stopped
The race car driver finished the race
The race car driver slowed down
The race car driver increased his speed
The race car driver slowed down
Between the and part of the race, the race car driver decreases his speed from to . If we look pasted this point on the graph, we see that he speeds back up and continue with the race, so the race didn't not end. He also didn't stop, because his speed never hit ; thus, he must have had to slow down for some reason, but then resumed the race.
