Vedmedyk [2.9K]

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!
