Question

The graph of g(x)g(x) is the graph of f(x)=x−2f(x)=x-2 reflected across the y-axis.

Which equation describes g?

A. g(x)=−x−2g(x)=−x-2

B.g(x)=−x+2g(x)=−x+2

C.g(x)=x+2g(x)=x+2

D.g(x)=−2x+2

Answer 1

We have f(x)=x-2, if it is reflected to the y-axis, all thay we need to do is calculate f(-x), it is f(-x)= (-x)-2= -x - 2, so the answer is A: g(x) = -x - 2
