Question

Which graph best represents a function with a domain of all real numbers greater than or

equal to 5?

Answer 1

(c)

Explanation:

You want the graph that has a domain of x ≥ 5.

Domain

The domain of a function is the set of x-values for which the function is defined. A domain of x ≥ 5 means the function is defined for x-values at least 5. The graph of the function will extend from x=5 indefinitely to the right.

Graph C is like that.
