Unformatted text preview: is the interval . Now we are ready to find the domain of , which consists of all that satisfy both of the following conditions: Condition 1: is in the domain of , Condition 2: is in the domain of . Because the domain of is , condition 1 is satisfied by all such that . Because the domain of is , the values are always in the domain of . That is, condition 2 is always satisfied. So conditions 1 and 2 are satisfied by all such that . Therefore, using interval notation , the domain of is . The answer is: For additional explanation, see your textbook: Section 2.7: Combining Functions and Domain of : ....
