Question

If f(x) = 11x – 5, then f^-1(x)=

Answer 1

Answer: $f^-^1(x)=\frac{x+5}{11}$

Step-by-step explanation:

To find the inverse, you replace the x with y, and y with x.

$x=11y-5$                       [add 5 on both sides]

$x+5=11y$                       [divide both sides by 11]

$\frac{x+5}{11} =y$

$f^-^1(x)=\frac{x+5}{11}$
