Question
In $3-6,$ each set represents a function. a. What is the domain of each function? b. What is the range of each function? c.Is the function one-to-one? $$\{(2,7),(3,7),(4,7),(5,7),(6,7)\}$$
Step 1
The domain of a function is the set of all possible input values (often referred to as 'x' values). In this case, the domain is the set of all first elements in each pair. So, the domain is $\{2,3,4,5,6\}$. Show more…
