Question

I need the explanation to understand pleasey= - (x+7)^2A.) Identify the coefficients (a, h, and k) B.) Tell whether the graph opens up or opens down. C.) Find the vertex. Write as a coordinate. D.) Find the axis of symmetry. Write as an equation. E.) Find two more points on the graph. You can choose what x - values to use. Write your points as coordinates (x, y).

Answer 1

h and k are the coordinates of the vertex

h = -7 k = 0 a = 1 a = number before the parenthesis

a) h is with the x

k is with the y

b) The graph opens down because there is a negative sign before the parenthesis.

c) Vertex are the coordinates h and k

Vertex = (-7, 0)

d)

the axis of symmetry is the red line

Axis of symmetry: x = -7

E) From the graph

P1 = (-6, -1)

P2 = (-8, -1)
