2-128.

For each equation below, find the - and -intercepts and the locator point , then write the equations in graphing form. Homework Help ✎

  1. -intercept:

    -intercept:

    Since there is only one -intercept, the vertex must be at the -intercept.

    -intercept:
    -intercept:
    vertex: 

  1. 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.
