Question

determine the range of the following graph:

Explanation:

Step1: Identify lowest y - value

The lowest point on the graph has a y - value of approximately - 9.

Step2: Identify highest y - value

The highest point on the graph has a y - value of 9.

Step3: Determine range

The range is all the y - values the graph takes. Since the graph has an open - circle at y = - 2 and a closed - circle at y = 2, the range is \(-9\leq y< - 2\) or \(-2 < y\leq9\).

Answer:

\(-9\leq y< - 2\) or \(-2 < y\leq9\)
