Answer
Graph the points (-1,-3) and (1,-3) and connect them with a straight horizontal line.
Work Step by Step
The graph of g(x) is f(x) changed first by horizontally shrinking by 2 (so the line is half as long), then reflected across the x-axis (so all of the y-values are multiplied by -1), and finally shifted vertically downward by 1 unit (so all of the y-values are decreased by 1).
