Answer:
x = 6
Step-by-step explanation:
We want to solve:
First, isolate the variable by moving all the terms with x to one side and all the constants to the other side:
Combining the fraction on the left, we get:
6/3 = 2, so:
2x = 12
Dividing both sides by 2 yields:
x = 6
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) =
