Answer:
A) 2nd graph
Step-by-step explanation:
The 1st graph shows a radical expression, where:
to find the inverse, replace f(x) with y, switch the x and the y, then solve for y. The only graph showing exponential growth is the 2nd graph (note how at 1 it's 1, at 2 it's 4, at 3 it will be 9, etc.)
