Which function has an axis of symmetry of x = −2? f(x) = (x − 1)2 2 f(x) = (x 1)2 − 2 f(x) = (x − 2)2 − 1 f(x) = (x 2)2 − 1

Ok, so that the axis of symmery is the x value of the vertex remember vertex formf(x)=a(x-h)^2+kh is the x valueso we wantxvalue=-2=hf(x)=a(x-(-2))^2+korf(x)=a(x+2)^2+kwe see that the latter is the answerf(x)=(x+2)^2-1
