Find the limit, as x approaches zero, of:
3x%2F%28x%5E3-x%29 First, factor an x from the denominator.
3cross%28x%29%2Fcross%28x%29%28x%5E2-1%29 Cancel the the indicated x's
3%2F%28x%5E2-1%29 Now you can see that, as x approaches zero, the denominator gets closer and closer to -1.
So the limit is3%2F%280-1%29 or -3
