Answer:
Option 3
Step-by-step explanation:
y = ⅗x - 9
Make x the subject
⅗x = y + 9
x = 5y/3 + 15
Interswitch variables
g^-1(x) = 5x/3 + 15
C
We want to find the inverse of g(x). One way to do this is to switch the g(x) and x in the original equation and then solve for g(x); that will give you the inverse.
Here, . Switch the g(x) and x to become: . Now solve for g(x) by isolating it:
Thus, the answer is C.
Hope this helps!
