Explore over 16 million step-by-step answers from our librarySubscribe to view answer. Last updated: 7/4/2022. The restrictions to the domain of a quotient will consist of the restrictions of each function as well as the restrictions on the reciprocal of the divisor. Once the restrictions are determined we can cancel factors and obtain an equivalent function as follows: It is important to note that 1 is not a restriction to the domain because the expression is defined as 0 when the numerator is 0. In this case, the domain of consists of all real numbers except −3 and 7, and the domain of consists of all real numbers except 7 and −7.

Fusce dui lectus, congue vel laoreet. However, it is useful at this point to know that the restrictions are an important part of the graph of rational functions. When we make that assumption, we do not need to determine the restrictions. Be sure to state the restrictions unless the problem states that the denominators are assumed to be nonzero. Step 3: Cancel common factors, if any. Given and, calculate and determine the restrictions. Depended upon the text you're using, this technicality with the domain may be ignored or glossed over, or else you may be required to make note of it.
