As long as you have the "a" in vertex form, you can graph the function by testing all values of x. Leaving your h and k as the numbers the represent.

-b/2a is your X for the equation/vertex. So once you find that you can sub it back into the equation to find the Y of your vertex

The vertex in the point where the quadratic splits down the middle. (h,k) is the vertex as shown below.

# data[].attributes.body
y = a(x - h)² + k.

# data[].attributes.body
y = ax² + bx + c

In order to graph a quadratic function you must know the two forms of a quadratic. The second form is called the vertex-form or the a-h-k form, y = a(x - h)² + k.
