F(x) = 9 - x 2 is ambiguous. I'm going to assume that you meant
f(x) = 9 - x^2. Use the symbol "^" to indicate exponentiation.
You are to find the inverse function.
1) replace f(x) with y.
2) interchange variables x and y: x = 9 - y^2
3) solve the resulting equation for y: If x = 9 - y^2, then y^2 = 9 - x, and
there are two correct results: y = + sqrt (9 - x) and y = - sqrt (9 - x)
4) replace "y" with "inverse function of x)."
When there are two results, as there are here, often it's best to accept the positive one.
So, let's say that the inverse of the given function is y = sqrt (9-x).
Since the domain of the sqrt function consists of zero and positive x, 9-x must be either zero or positive; thus, x: (-infinity, 9)
Check: is x=10 OK? No, because we'd then have sqrt(-1).
is x=9 OK? Yes, because we'd then have sqrt(0) = 0
And so on.

Good luck with the quiz!!!
Answer:
X(6, 1), Y(-4, 0), Z(-1, 3)
Step-by-step explanation:
When reflecting an image across the y-axis, (i.e, across a vertical line at the position x = 0), All you need to do is negate the x coordinate of each point, so:
(-6, 1) becomes (6, 1)
(4, 0) becomes (-4, 0)
(1, 3) becomes (-1, 3)
