Respuesta :

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

answer
inverse
f-1(x) = 
x/2 + 2
Astute
Hey there!

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

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


[tex]solve \ 2x-4= y \ for \ x [/tex]

Substitute 
[tex]y=x[/tex]

Your correct answer would be [tex]\boxed{ \frac{x+2}{2} }[/tex]   

Hope this helps.
