Question

Which function below is the inverse of f(x) = x2 − 36?. . x squared over 36. . ±6square root of x. . 1 over quantity x squared minus 36. . ±square root of the quantity x plus 36

Answer 1

The function is f(x) = x^2 - 36. => y = x^2 - 36. To find the inverse function, you can exchange the variables (x,y) and the solve for the new y => x = y^2 - 36 => y^2 = x + 36 => y = +/- sqrt of x + 36. So, the answer is +/- square root of the quantity x plus 36
