Question

1. determine whether each graphs domain is discrete or continuous.

Explanation:

for the first graph (left):

Step1: Recall domain types

Discrete domain: values are distinct, separate (e.g., whole numbers, specific points). Continuous domain: values form an interval (connected, all real numbers in a range).

Step2: Analyze the first graph

The first graph has separate, unconnected points (dots). So its domain consists of distinct, individual x - values (not a continuous interval). Thus, the domain is discrete.

for the second graph (right):

Step1: Recall domain types

As before, discrete (separate points) vs. continuous (connected, interval).

Step2: Analyze the second graph

The second graph is a line segment (connected line), meaning the x - values form a continuous interval (all real numbers between the start and end x - values of the line). Thus, the domain is continuous.

Answer:

• First (left) graph: Discrete domain.
• Second (right) graph: Continuous domain.
