The inverse function of the above function is f(x) =
You can find the inverse of any function by switching the f(x) and x terms. Once you have done that, solve for the new f(x). Finally, what you'll have remaining is the inverse function. The work is done for you below:
f(x) = ----> Switch the x and f(x)
x = ---> square both sides
= 2f(x) + 2 ---> subtract 2 from both sides
- 2 = 2f(x) ----> divide both sides by 2
= f(x) ----> switch the order for formatting sake.
f(x) =
Step 1) Cross multiply 55(12) to get 825
Step 2) Cross multiply 22(n) to get 22n
Step 3) Set up your equation: 22n=825
Step 4) Solve equation by dividing 825/22= 37.5
Your anser is N=37.5
