Question

If g(x)=3+x+2e^x, find g^(−1)(5)

Answer 1

First find the inverse, you can do this by replacing g(x) by y and then solving for x. Then substitute y=5.

Answer 2

3 + y + 2e^y? then plug in 5?

Answer 3

No, replace g(x) with y. So you get:
\[ y=3+x+2e^x \]
Then solve for x and plug in y=5 (or you could plug it in the reverse order).

Answer 4

Wait, that is very hard to do. Are you sure it's the inverse of the function?

Answer 5

yes its the inverse of the function
