Which function below is the inverse of f(x) = x2 − 9?

±square root of the quantity x plus 9

x squared over 9

±three times the square root of x

1 over quantity x squared minus 9

Answer 1

If \[f(x)=5x+3\]to solve for the inverse of f(x), let\[y=5x+3\]switch the variables positions as such\[x=5y+3\]and solve for y\[y=(x-3)/5\]that would be the inverse of the original function
