a. w(2)=5

Explanation:

Step1: Understand the function \(g(x)\)

The function \(g(x)\) is represented by a graph. We need to find the \(x\)-values for which \(y = g(x)=4\).

Step2: Analyze the graph

Looking at the graph, when \(y = 4\), we can see that the \(x\)-values are \(x=- 2\) and \(x = 2\) (by observing the points where the horizontal line \(y = 4\) intersects the graph of \(y=g(x)\)).

Answer:

B. -2 and 2
