We have now successfully removed both square roots. Let us continue on with the solution. Expand right hand side: x−1 = (x 2 − 10x + 25)/4. It is a Quadratic Equation! So let us put it in ... WebAs x goes to infinity, the denominator goes to infinity, so the whole fraction goes to zero and the square root of zero is zero, so f (x) goes to zero. As x goes to infinity, the denominator goes to negative infinity, but we can't take the square root of a negative number, so f (x) doesn't have a limit as x goes to infinity.
