When in this form the form for the vertex can be found in your textbook. x = a(y - k)² + h and the vertex is (h,k). The way you wrote the expression is incorrect. Note how I wrote it here in this submission. So an example similar to the one you tried to give you would have: x = (y - 5)² - 3 and the vertex would be (-3, 5). It is important to be clear and accurate when asking questions and doing your work. It helps prevent miscommunication error and mistakes.

The vertex of a parabola doe not provide enough information to graph anything - other than the vertex!

The vertex is either the minimum (very bottom) or maximum (very top) of a parabola.

The vertex would be the point where both sides of the parabola meet.

To find the value of a in a parabola opening up or down subtract the y-value of the parabola at the vertex from the y-value of the point on the parabola that is one unit to the right of the vertex.

the vertex of a parabola is the 2 x-intercepts times-ed and then divided by two (if there is only 1 x-intercept then that is the vertex)
