Question

match each part of the formula with its meaning
a
h
k
(h, k)
x = h
vertex
horizontal movement of the parabola
axis of symmetry
vertical movement of the parabola
slope, also tell the direction that the parabola opens
possible points: 5

Explanation:

In the vertex - form of a parabola equation $y=a(x - h)^2 + k$, the coefficient $a$ determines the slope and the direction of the parabola opening. The value $h$ represents the horizontal movement of the parabola. The value $k$ represents the vertical movement of the parabola. The point $(h,k)$ is the vertex of the parabola. The equation $x = h$ is the axis of symmetry of the parabola.

Answer:

a: slope, also tell the direction that the parabola opens
h: horizontal movement of the parabola
k: vertical movement of the parabola
(h,k): vertex
x = h: axis of symmetry
