Which function, g or h, is the inverse function for function ƒ?

B.

Step-by-step explanation:

Remember that graphically, a function and its inverse are reflections over the line y = x.

Given the graph of f, we see that h is not a reflection over the line y = x. So, we can eliminate choices A and C.

Function g is indeed a reflection of y over the line y = x. A function and its inverse is not its reflection over the x-axis so D is incorrect.

Hence, our answer is B.
