4-66.
Change the equation in the previous problem so that the parabola has only one x-intercept.
Remember that the parabola's vertex was
Remember that the only way for a parabola to have only one x-intercept is to have the vertex touching the x-axis.
To make it so the equation only has one x-intercept, you must make the vertex's y value equal 0.
