    Hey there!

    Your question states: Find the inverse of the function f(x) = 2x – 4

    → We need to remember that when finding the inverse of a function, this would mean that we would find the complete opposite of the whole expression listed above.

    solve \ 2x-4= y \ for \ x

    Substitute 
    y=x

    Your correct answer would be \boxed{ \frac{x+2}{2} }   

    Hope this helps.

    f(x) = 2x – 4
    inverse
    x = 2y – 4
    2y = x + 4
      y = x/2 + 2

    answer
    inverse
    f-1(x) = x/2 + 2
