Question

Find the inverse of the function F(x)=2x-4

Answer 1

f^-1(x)=( x + 4 ) / 2

Explanation:

by putting f(x) = y , we got the x in y i.e. x = (y+4)/2.

then replace y with x, we get the inverse of function f(x).

Answer 2

the inverse of F(x)=2x-4 is f^-1(x) = (x + 4) / 2.

In simple terms, the inverse function takes the output of the original function and gives you the original input back. So, if you input 2 into the original function, you get 6 as the output. If you input 6 into the inverse function, you get 2 as the output.
