Final answer:
The domain of the function with the given ordered pairs {(0,1),(1,2),(2,4),(3,6)} is the set of the first elements from each pair, which is {0, 1, 2, 3}.
Step-by-step explanation:
The domain of a function refers to the set of all possible input values (usually represented by x) that the function can accept. In the context of the given set of ordered pairs, {(0,1),(1,2),(2,4),(3,6)}, the domain is simply the set of all the first elements in each ordered pair. Therefore, the domain for this function is {0, 1, 2, 3}.
