for a limit where x approaches negative infinity for a rational function with a square root in the denominator, to simplify can I multiply the top by 1/x and the bottom by 1/sqrt(x^2)? wouldn't that cancel the negative?

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
