Example Question #501 : Ssat Upper Level Quantitative (Math)
Find the y-intercept:
Rewrite the equation in slope-intercept form, .
The y-intercept is , which is .
Example Question #11 : X And Y Intercept
What is the -intercept of the graph of the function
The graph has no -intercept.
The -intercept of the graph of a function is the point at which it intersects the -axis - that is, at which . This point is , so evaluate :
The -intercept is .
Example Question #222 : Coordinate Geometry
Define a function . Which of the following is the -intercept of the graph of ?
The -intercept of the graph of a function has 0 as its -coordinate, since it is defined to be the point at which it crosses the -axis. Its -coordinate is , which can be found using substitution, as follows:
The correct choice is .
Example Question #223 : Coordinate Geometry
Define a function . Which of the following is an -intercept of the graph of ?
(a)
(b)
Neither (a) nor (b)
(b), but not (a)
Both (a) and (b)
(a), but not (b)
Neither (a) nor (b)
An -intercept of the graph of a function has 0 as its -coordinate, since it is defined to be a point at which it crosses the -axis. Its -coordinate is a value of for which .
We can most easily determine whether is a point on the graph of by proving or disproving that , which we can do by substituting 2 for :
, so is not an -intercept.
Similarly, substituting 3 for :
, so is not an -intercept.
Example Question #281 : Geometry
Define . The graphs of and a second function, , intersect at their common -intercept. Which of the following could be the definition of ?
An -intercept of the graph of a function has 0 as its -coordinate, since it is defined to be a point at which it crosses the -axis. Its -coordinate is a value of for which , which can be found as follows:
Substituting the definition, we get
Solving for by subtracting 7 from both sides, then dividing both sides by 2:
The -intercept of the graph of is the point .
To determine which of the four choices is correct, substitute for and determine for which definition of it holds that .
can be eliminated immediately as a choice since it cannot take the value 0.
:
The correct choice is .
