Refer to the image below for the graph.
Work Step by Step
$g(x) = f(x)+1$ means that the function $g(x)$ involves a vertical shit of 1 unit upward of the function $f(x)$. This means that the points of $f(x)$ will be moved 1 unit upward to find the corresponding points in $g(x)$. Doing this gives the points: $(-2, 3)$, $(0, 3)$, and $(2, 3)$ Plot these points then connect the using a line segment. (refer to the attached image in the answer part above).
