The domain and f^1(x)
TEA [102]

B

To solve for the inverse, just swap the x and y and solve for the new y.

y=\sqrt{x} -8

x=\sqrt{y}-8

x+8=\sqrt{y}

(x+8)^2=y

Then inspect both functions for the domain.

In the original function, x has to be greater than or equal to 0 or else you would have a negative square root which is impossible.

The inverse function has no limitations as any x could make that true.

The main things that will limit domain is square root of negative or divide by zero.

Therefore, x>=0 is the only domain restriction.

Answer: d, eight and fifty-three thousandths

The numbers after (.053) are thousandths because the whole number (8.053) consists of 4 numbers the same way a 1000 does.

Sorry I found the last bit harder to put into words, but I hope it helps :)
