  c. For each x-value in the domain, there is exactly one corresponding y-value.

Step-by-step explanation:

You can think of this as a vocabulary question. It helps a lot if you understand the language.

Domain: the set of x-values for which a relation is defined.

x-value: a member of the domain; the first member of an ordered pair.

y-value: the second member of an (x, y) ordered pair.

Relation: a set of (x, y) ordered pairs. A relation can be presented as a table, graph, set of ordered pairs, or an equation.

Function: a relation in which no x-value is repeated; a relation that has exactly one y-value corresponding to each x-value.

Additional comment

The graph of a function passes the vertical line test. That is, any vertical line drawn on the graph will intersect the graph in no more than one point. This is equivalent to saying there is only one y for each x.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
