Question

this is the graph of a linear function. what are the domain and the range of the function? domain: range:

Explanation:

Step1: Identify domain from graph

The graph extends infinitely to the left along the x - axis. The left - most visible point has an x - coordinate that seems to be approaching negative infinity, and there is no right - most end shown. So the domain is all real numbers, which can be written as $(-\infty,\infty)$.

Step2: Identify range from graph

The graph extends infinitely upwards along the y - axis and has a lowest visible point. Since it goes up without bound and has no upper - limit shown and has a lowest value that seems to be approaching negative infinity, the range is all real numbers, which can be written as $(-\infty,\infty)$.

Answer:

Domain: $(-\infty,\infty)$
Range: $(-\infty,\infty)$
