For this case we have the following equation:
\(y = 100 - x ^ 2
\)
From here, we must clear the value of x.
We have then:
\(x^2 = 100 - y
x = +/-\sqrt{100 - y}\)
Then, returning the change of variables we have:
\(y=+/-\sqrt{100 - x}\)
Answer:
The invserse of the given function is:
\(y=+/-\sqrt{100 - x}\)
option A
