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