Answer:

0

Explanation:

We are given a function
f(x) = 3(x+2)-4.

To find its inverse, we will put this function equal to y (or any other variable) and make x the subject.


y = 3(x+2)-4


y+4 = 3x+6


y+4-6 = 3x


(y-2)/(3) = x

So,
f'(x) = (x-2)/(3)

Now put x = 2 in this to get the value of inverse of this function:


f'(2)= ((2)-2)/(3)
= 0

Therefore, the value of the inverse of this function when x = 2 is 0.
