Question

A coordinate plane shows both the axes ranging from negative 12 to 12 in increments of 1. An upward solid line with arrows at both ends passes through origin and extends to quadrants 1 and 3. The arrow points to the unmarked points left parenthesis negative 9 comma negative 5.3 right parenthesis and left parenthesis 7.5 comma 4.5 right parenthesis.

Describe the domain of the linear function on the graph.

x is all real numbers.

−9≤x≤7

x≥−9

−9<x<7

Answer 1

The domain of the linear function on the graph is -9 ≤ x ≤ 7, which means that the function is defined for all real numbers greater than or equal to -9 and less than or equal to 7.
