The inverse function is f(x) = \frac{x + 4}{3} - 2, which makes the inverse at x = 2 equal to 0.


All inverse functions can be found by switching the x and f(x) values. Once that is done, solve for the new f(x) value. The result will be the inverse of the original function. The step-by-step process is below.


f(x) = 3(x + 2) - 4 ----> Switch the x and f(x)

x = 3(f(x) + 2) - 4 ----> Add 4 to both sides

x + 4 = 3(f(x) + 2) ----> Divide both sides by 3

\frac{x + 4}{3} = f(x) + 2 ----> Subtract 2 from both sides.

f(x) = \frac{x + 4}{3} - 2


The end is your inverse function. So then we can evaluate when x = 2.


f(x) = \frac{x + 4}{3} - 2

f(2) = \frac{2 + 4}{3} - 2

f(2) = \frac{6}{3} - 2

f(2) = 2 - 2

f(2) = 0
