To find the inverse function of f where f(x)=35x

Expert Solution

Answer to Problem 40E

Value of the inverse function is f1(x)=3x5

Explanation of Solution

Given information: A function f(x)=35x.

Calculation: Put f(x)=y

  f(x)=35xy=35x

Now solve for x .

  5x=3yx=3y5

Interchange y and x .

  y=3x5

Therefore, the inverse function is

  f1(x)=3x5
