2-128.

For each equation below, find the - and

*-intercepts and the locator point*

-intercept:-intercept:Since there is only one

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

vertex:

Start by finding 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.
