Question

Tell me what the letters A, H, and K stand for in the vertex form.

Answer 1

Greetings.

The answer is

a = determines the shape of parabola (upward, downward, narrow or wide)

h = determines the transformation of the graph for x-axis (For example, (x+1)², the graph would move from x=0 to x=-1

k = determines the transformation of the graph for y-axis. (For example, x²+1, the graph would move from y = 0 to y = 1.
