Math 1314 Test 2 Review 2 Limits at Infinity: If the degree of the numerator is smaller than the degree of the denominator, then . 0 ) ( ) ( lim = x g x f x If the degree of the numerator is the same as the degree of the denominator, then you can find ) ( ) ( lim x g x f x by making a fraction from the leading coefficients of the numerator and denominator and then reducing to lowest terms. If the degree of the numerator is larger than the degree of the denominator, then it’s best to work the problem by dividing each term by the highest power of x in the denominator and simplifying. You can then decide if the function approaches or - , depending on the relative powers and the coefficients. 5. 3 2 1 2 2 lim x x x x - + - - 6. 1 6 5 2 lim + - x x x 7. x x x x + - + + - 1 1 lim 2 3 8.
