Question

What is the equation of the axis of symmetry for the function shown below?

y-2=-(x+5)^2

A. y=2
B. X=5
c. x=2
d. x=-5

Answer 1

axis of symmetry is for the x value.
so you can rule out option A.

Answer 2

formula is x = -b/2a

Answer 3

convert it into a quadratic, or graph it to find the axis of symmetry.

Answer 4

so the answer is 5?

Please take a look at Parabolas section, left side.

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

In your problem

(x-h) = (x+5)
x-h = x+5
h=-5

I think -5 is your answer.

Hope the formula sheet will help in the future.

Answer 6

thanks for the help :)

Answer 7

Anytime :)
