Answer:
[tex]f^{-1} = x+4[/tex]
Step-by-step explanation:
f(x) = x- 4
To find inverse function , we replace f(x) b y
y = x- 4
Replace y with x and replace x with y
x = y - 4
Now we solve for y
x = y - 4
Add 4 on both sides
x + 4 = y
Now we replace y with f^-1(x)
[tex]f^{-1} = x+4[/tex]
Inverse of function f(x) = x-4 is f^-1(x) = x+ 4
