Analyze and Sketch Function Graphs Practice Test

A student's distance from home (in miles) changes during a bike ride. The distance increases at a constant rate from 0 miles at 1:00 PM to 6 miles at 2:00 PM. Then the student rides back toward home at a constant rate and is 2 miles from home at 3:00 PM. Which sketch best matches this description (time on the x-axis, distance on the y-axis)?

A student walks away from home, stops for a snack, then walks back home. Distance from home (y) versus time (x) should:

• increase at first,
• then stay constant for a while,
• then decrease back toward 0.

Which choice matches that situation?
