question 13 of 22
what is the domain of the function shown in the table?

x	y
5	-3
7	3
9	4

a. {-4, -3, 3, 4}
b. {3, 5, 7, 9}
c. {-4, -3, 3, 4, 5, 7, 9}
d. (3, -4), (5, -3), (7, 3), (9, 4)

Explanation:

The domain of a function is the set of all input values (x - values) for which the function is defined. In the given table, the x - values are 3, 5, 7, and 9. Option A is the set of y - values, Option C combines x and y values, and Option D is the set of ordered pairs (which represent the function's points, not the domain). So the domain is the set of x - values {3, 5, 7, 9}.

Answer:

B. {3, 5, 7, 9}
