+ , where n > m. As x approaches infinity, the highest power of x in the numerator dominates the value of the numerator, and the highest power of x in the denominator dominates the value of the denominator. This means that we can ignore all the lower-order terms, and simply consider the behavior of the highest-order terms. In this case, the highest-order term in the numerator is 2x4, and the highest-order term in the denominator is x3.
