Question 223653: Given:y=2(x-5)^2+63, what is the axis of symmetry?

You can put this solution on YOUR website!
y=2%28x-5%29%5E2%2B63
I'm going to put this into standard form first:
y=2%28x%5E2-10x%2B25%29%2B63
y=2x%5E2-20%2B50%2B63
y=2x%5E2-20%2B113
-----------------
Axis of symmetry from standard form equation is given as
x=-b%2F2a
x=20%2F4
highlight%28x=5%29
-----------------
Note that you could also read it off directly from the vertex form:
x=-h where h is -5.
