Given the function f(x) = 3(x+2) - 4, solve for the inverse function when x = 2.
I need help on this question!! I get really confused when it comes to the inverse of an equation.

solve 3(x+2)-4 =2, what do you get ? x =??

I keep getting 3x=0. Am I supposed to use the distributive property first?

loser66 · Answer

3(x +2) -4 =2
3(x+2) =6
x+2 = 2
x =0, get this part??

anonymous · Answer

That makes more sense.

Now, approach the problem on this way:
$f(\color{red}{x}) = a\f^{-}(a) =\color{red}{x}$
Ok then??

You just tell me whether you got the previous post or not. Your problem is not done yet.

anonymous · Answer

I still don't really get it.

anonymous · Answer

I get that you flip the two. So if x is zero what would the a symbolize?
