1-20.

Continuous functions must have connected pieces. There can be no jumps or holes. What happens to *g*(*x*) at *x* = 3 and at *x* = 5?

Area of Rectangle A: 2 × 3 = 6 units^{2}

Area of Rectangle B: 3 × 2 = 6 units^{2}

Area of Rectangle C: 7 × 3 = 21 units^{2}

Rectangle A + Rectangle B + Rectangle C = 33 units^{2}

The shape of the graph should help answer this question.

Use the eTool below to examine the graph of *g*(*x*).
