.
Example Question #11 : Intercepts And Curves
What is the x-intercept of ?
To find the x-intercept, we set and solve.
Subtract from both sides.
Divide both sides by .
Simplify.
Example Question #12 : Intercepts And Curves
What is the x-intercept of the following equation?
10
-5
2
5
0
5
We want to find the x-intercept, which is the point at which the graph crosses the x-axis. Every point on the x-axis has a y-value of 0. Thus, to find the x-intercept we just need to plug 0 in for y.
Thus, .
Dividing both sides by , we get
.
Example Question #13 : Intercepts And Curves
What is the y-intercept of the following curve?
The y-intercept of a curve is the value of that curve when the x-coordinate is . Thus, we plug in
to our equation, yielding
