Answer:

$\displaystyle {f}^{ - 1}(x) = \frac{1}{4} (x - 18x + 85)$

Step-by-step explanation:

we would like to find the inverse of the following function:

$\displaystyle f(x) = 9 + \sqrt{4x - 4}$

to do so substitute y for f(x):

$\displaystyle y= 9 + \sqrt{4x - 4}$

interchange variables:

$\displaystyle x= 9 + \sqrt{4y - 4}$

cancel 9 from both sides:

$\displaystyle \sqrt{4y - 4} = x - 9$

square both sides:

$\displaystyle 4y - 4= x - 18x + 81$

add 4 in both sides:

$\displaystyle 4y = x - 18x + 85$

divide both sides by 4:

$\displaystyle y = \frac{1}{4} (x - 18x + 85)$

substitute back:

$\displaystyle {f}^{ - 1}(x) = \frac{1}{4} (x - 18x + 85)$

and we're done!
