Answer:
[tex]f^{-1}[/tex](x) = [tex]\frac{x}{2}[/tex]
Step-by-step explanation:
let y = 2x
Rearrange making x the subject
divide both sides by 2
[tex]\frac{y}{2}[/tex] = x
changing y back into terms of x
[tex]f^{-1}[/tex](x) = [tex]\frac{x}{2}[/tex]
Answer:
f^-1(x) = x/2
Step-by-step explanation:
To find the inverse of a function, we exchange x and y and then solve for y
y =2x
Exchange x and y
x = 2y
and then solve for y
Divide by 2
x/2 =y
The inverse function
f^-1(x) = x/2
