Question

Please help!

consider the function f(x)=-(x+2)^2+4
2 + 4.

a) in what form is this quadratic function written? _________________________


b) list the values of the following parameters

a = ______

h = ______

k = ______

vertex = ___________

c) what will the a parameter do to this function?

Answer 1

Below,

Explanation:

f(x)=-(x+2)^2+4

(a) Vertex form

(b) a = -1 , h = -2 and k = 4.

vertex = (-2, 4)

(c) The value of a, -1 will invert it vertically or we can describe it as a reflection in the line y = 4. The graph will change from a U shape to a ∩ shape.
