the graph of which function has a y - intercept of 3?

Explanation:

Step1: Recall y - intercept definition

The y - intercept is the value of y when x = 0. We need to check the graphs at x = 0.

Step2: Examine the first graph

In the first graph, when x = 0, y = 3.

Step3: Examine the second graph

In the second graph, when x = 0, y = 1.

Answer:

The first graph.
