Giving brainliest :)
Verizon [17]

Answer:

f^{-1}(x)=x^2+1

Step-by-step explanation:

The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y

Original Equation:

f(x)=\sqrt{x-1}\\

write f(x) as y (since that's what it represents)

y=\sqrt{x-1}

Swap x and y

x=\sqrt{y-1}

Square both sides

x^2=y-1

Add 1 to both sides

x^2+1=y

So this gives you the equation:

f^{-1}(x)=x^2+1
