2-128.
For each equation below, find the
-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.
