Which statement best describes the domain of the function represented in the graph?

Given:

The graph of a function.

To find:

The correct statement for the domain of the given function graph.

Solution:

Domain is the set of x-values for which the function is defined or it is the set  of input values.

From the given graph it is clear that it is a linear function with end points (1,2) and (9,14).

So, the given function is defined for . Here 1 and 9 are including in the set of x-values.

Therefore, the correct option is C, i.e., or x between 1 and 9, inclusive.
