Finding Axis of symmetry

f(x) = (x − 5)2 + 2 i need a axis of symmetry

Your Answer:

If by f(x) = (x − 5)2 + 2
you mean:



then we can use the fact that this equation is in standard form. This means that



gives us what we need to determine the axis of symmetry.
Therefore the axis of symmetry is:

x=5
