To find the inverse function of f where f(x)=2x+1

Expert Solution

Answer to Problem 37E

  f1(x)=x12

Explanation of Solution

Given information: A function f(x)=2x+1.

Calculation: Put f(x)=y

  f(x)=2x+1y=2x+1

Interchange y and x .

  x=2y+1

Now solve for y .

  2y=x1y=x12

Therefore, the inverse function is

  f1(x)=x12
