All rights reserved Slide LIMIT PROPERTIES (continued): The limit of a power is the power of the limit, and the limit of a root is the root of the limit. That is, for any positive integer n, and assuming that L ≥ 0 when n is even. Algebraic Limits and Continuity 2012 Pearson Education, Inc. All rights reserved Slide LIMIT PROPERTIES (continued): The limit of a sum or difference is the sum or difference of the limits. The limit of a product is the product of the limits. Algebraic Limits and Continuity 2012 Pearson Education, Inc. All rights reserved Slide LIMIT PROPERTIES (concluded): The limit of a quotient is the quotient of the limits. The limit of a constant times a function is the constant times the limit. Algebraic Limits and Continuity 2012 Pearson Education, Inc.
