Question

determine the range of the following graph:

Explanation:

Step1: Identify min - max y - values

The lowest y - value of the graph is at the bottom - most point and the highest y - value is at the top - most point.
The lowest y - value is $y=-1$ and the highest y - value is $y = 8$.

Step2: Write the range

The range of a function is the set of all possible output values (y - values). Since the graph includes all y - values between - 1 and 8 (inclusive, as the endpoints are solid dots), the range is written in interval notation as $[-1,8]$.

Answer:

$[-1,8]$
