Question

determine the range of the following graph:

Explanation:

Step1: Identify min and max y - values

The lowest y - value of the graph is $y=-2$ (the left - most point) and the highest y - value is $y = 8$ (the peak).

Step2: Write the range

The range is all the possible y - values of the function. Since the graph is continuous between these points, the range is $-2\leq y\leq8$.

Answer:

$-2\leq y\leq8$
