Solution Steps

Step 1: Identify two points on the original graph

Two points on the graph of $y=g(x)$ are $(2,3)$ and $(3,4)$.

Step 2: Apply the transformation

The graph of $y=2g(x)$ is a vertical stretch of the graph of $y=g(x)$ by a factor of 2. This means we multiply the y-coordinates of the points on the graph of $y=g(x)$ by 2.

For the point $(2,3)$, the transformed point is $(2, 2 \cdot 3) = (2,6)$. For the point $(3,4)$, the transformed point is $(3, 2 \cdot 4) = (3,8)$.

Step 3: Plot the transformed points and draw the line.

Plot the points $(2,6)$ and $(3,8)$ and draw the line segment connecting them.

Final Answer

The graph of $y=2g(x)$ is the line segment connecting the points $(2,6)$ and $(3,8)$.
