7-61.

For each function, determine the ‑ and

*‑intercepts and the locator point (*

*). If you have not already done so, write the equations in graphing form.*

-intercept:-intercept:Since there is only one

-intercept, the vertex must be at the-intercept.-intercept:-intercept:

vertex:

Start by determining the

- and-intercepts.To find the

-coordinate of the vertex, average the-intercepts.To find the

-coordinate of the vertex, substitute the-coordinate of the vertex into the given equation and solve for.Now write the equation in graphing form.
