Question

determine the range of the following graph:

Explanation:

Step1: Identify lowest y - value

The lowest point of the graph has a y - value of 1 (solid dot).

Step2: Identify highest y - value

The highest point of the graph has a y - value of 11 (open dot).

Step3: Write the range

The range is all the y - values between the lowest and highest. Since the lowest is 1 (inclusive) and the highest is 11 (exclusive), the range is $1\leq y<11$.

Answer:

$1\leq y<11$
