24) Plot the graph of the function.

Solution:

The graph shows a piecewise function. From x=-5 to x=0 (exclusive of 0), the function is linear, passing through (-5, 6) and approaching (0, 4). At x=0, there is a hollow circle at y=4. From x=0 (exclusive of 0) to x=7, the function is linear, passing through (0, 2) and (7, -4).

Answer: The graph of the function is shown above.
