Question

Determine the axis of symmetry for the function f(x) = −2(x + 3)2 − 5.

x = 3
x = −3
x = 5
x = −5

Answer 1

So this is a quadratic in the vertex form

f(x) = a(x-h)^2+k

where the vertex is (h,k) and the axis of symmetry is x=h

so here h=-3, right?
so then the axis of symmetry is x=h, plug it in

Answer 2

so... x=3?

Answer 3

-3 not 3

Answer 4

oh. oops haha. ty :D

Answer 5

f(x) = a(x-h)^2+k

3=-h
so h=-3

Thank youuuu
