Which of the following equations represents the inverse of y = e2x - 9?

Important:  write this function as y = e^(2x) - 9.  " ^ " indicates exponentiation.

To find the inverse function:

1) interchange x and y.  y becomes x and x becomes y:  x = e^(2y) - 9
2) solve this result for y:

             e^(2y) = x + 9                   Take the natural log of both sides:

              2y = ln(x+9) (domain is restricted to "x is greater than -9")

                            ln(x+9)
            Then y =
                               2

This is the inverse function of y = e^(2x) - 9.

Ithink the answer is c just trying to others

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
