tutorial.math.lamar.edu › InverseFunctionsJun 19, 2021 · Here are the first few steps. y = √ x − 3 x = √ y − 3 y = x − 3 x = y − 3. Now, to solve for y y we will need to first square both sides and then proceed as normal. x = √ y − 3 x 2 = y − 3 x 2 + 3 = y x = y − 3 x 2 = y − 3 x 2 + 3 = y. This inverse is then, g − 1 ( x) = x 2 + 3 g − 1 ( x) = x 2 + 3.
