Question

What is the axis of symmetry for f(x)=2x^2-8x+8?

x=-2

x=-3

x=3

x=2

Answer 1

axis of symmetry : x = -b/(2a)

Answer 2

try completing the square. do know how?

Answer 3

once u have the equation in the form
\[ y-k=A(x-h)^2 \]
u can get all the information u might want

Answer 4

h will always = -b/2a

Answer 5

so it would be 8/2(2) which would be reduced to 2 right?

Answer 6

yes

Answer 7

alright thank you.
