Question

Identify the axis of symmetry for the graph of f(x) = -(x - 4)2 - 6.

x=?

Answer 1

x = 4 ?

Answer 2

x = -7

Answer 3

how'd you guys get those answers?

Answer 4

i may be wrong just rearranged to find x see what others get though

Answer 5

You get the answer by finding the vertex of the function
Vx = -b/2a

so by expanding the bracket you get f(x) = -x^2+8 x-22

so Vx = -8 / -2 = 4

so equation of axis of symmetry is x = 4

Answer 6

the axis of symmetry is the vertex
The equation above is in vertex form
y = a(x - h) + k
where h is the x value of the vertex and k is the y value of the vertex

h is always opposite of the sign while k isnt

so since your equation is f(x) = -(x - 4)^2 - 6 your vertex is (4,-6). The axis of symmetry is your x value so x = 4
