## Lemanual one year ago Please help me solve this problem Let f(x) = x2 − 16. Find f−1(x). 4 square root of x ± square root of x plus 16 x squared over 16 1 over quantity of x squared minus 16

1. Nnesha

it's f^{-1}(x) inverse f(x) is same as y so you can write it as $\huge\rm \color{red}{y}=\color{blue}{x}^2-16$ to find inverse switch x and y $\huge\rm \color{blue}{x}=\color{reD}{y}^2-16$ now solve for y

2. Nnesha

can you solve for y?
