Question

match each part of the formula with its meaning
a: slope; also tell the direction that the parabola opens.
h: vertical movement of the parabolak: horizontal movement of the parabola(h, k): vertexx = h: axis of symmetry

Explanation:

In the vertex - form of a parabola's equation $y=a(x - h)^2+k$, the coefficient $a$ determines the direction of the parabola's opening (if $a>0$, it opens up; if $a < 0$, it opens down) and its steepness, not slope in the linear - sense. The value of $h$ represents the horizontal shift of the parabola, $k$ represents the vertical shift. The point $(h,k)$ is the vertex of the parabola, and the line $x = h$ is the axis of symmetry about which the parabola is symmetric.

Answer:

a - slope; also tell the direction that the parabola opens. (Incorrect, it determines opening direction and steepness)
h - horizontal movement of the parabola (Correct)
k - vertical movement of the parabola (Correct)
(h, k) - vertex (Correct)
x = h - axis of symmetry (Correct)
