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

  1. -intercept:


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


  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.
