Question

Consider this function.
(r) = -3r + 3
Which graph represents the inverse of function ?

Answer 1

9514 1404 393

Answer:

C. graph Y

Explanation:

Starting with f(r) = -3r +3, the inverse function can be found from ...

r = f(y)

r = -3y +3

r -3 = -3y

(r -3)/-3 = y

y = -1/3r +1

The inverse function will have a slightly negative slope and a y-intercept of 1. This matches graph Y.
