You are correct that as x approaches zero, the numerator will approach negative infinity. So the question relies on the denominator now. You need to see if the sign will change. Have you tried plotting it?
I plotted the equation and the denominator and the equation looks to go to infinity (how do i show this without graph) and the denominator varies between -1 and 1. could you pleasee explain what you mean by "You need to see if the sign will change".
Thanks for the reply
As x approaches zero, the denominator will approach a negative finite amount. If you have some numerator which approaches negative infinity then we have a negative over a negative giving a positive sign in the result. So it seems to me the answer is positive infinity.
