In order to find the inverse equation, we need to first switch the x and y portions of the formula. Since we are presented with what y is equal to, we will then just solve for y again after the inverse is applied.

So, switching the letters results in x = 100 - y2. Now solve for y. First, apply (-x) and (-y2) to each side. This results in y2 = 100 - x. To get rid of the square, apply the square root to each side. This results in the answer:

y = 10 - sqrt(x), where sqrt is square root (something not available on the keyboard).

Answer:

\(y =\sqrt{ 100-x}\)

Step-by-step explanation:

Given : \(y = 100-x^2\)

To Find: inverse

Solution:

\(y = 100-x^2\)

Replace x with y and y with x

\(x = 100-y^2\)

Now find the value of y

\(y^2 = 100-x\)

\(y =\sqrt{ 100-x}\)

Thus the inverse  is \(y =\sqrt{ 100-x}\)

Hence the inverse of \(y = 100-x^2\)  is \(y =\sqrt{ 100-x}\)
