given the graph, when is the graph increasing? it does not increase (-7,7) (-2,5) (-∞,∞)

Explanation:

Step1: Recall increasing - graph definition

A graph of a function $y = f(x)$ is increasing when, as $x$ increases, $y$ also increases. For a linear graph (which seems to be the case here as it looks like a straight - line), if the slope is positive, the function is increasing over its entire domain.

Step2: Analyze the given graph

Since it is a straight - line with a positive slope, the $y$ - value increases as the $x$ - value increases for all real values of $x$.

Answer:

$(-\infty,\infty)$
