Question

Lidentify the domain of the function shown in the graph

O A 15257
O B. 19334
O C. 221
O D. All real numbers

Answer 1

B.

Explanation:

the visible line is the defined function.

this line goes from x=1 to x=4, and has the functional results from y=1 to y=7.

the domain is the valid interval of the input variable (typically x), while the range is the valid inescapable of the result variable (typically y).

so, B is the right answer.
