How do you do b, c,d?

Step-by-step explanation:

(b) x is at 2 twice, and -2 twice.

y is at 2 three times, and -2 three times.

The graph that fits is I.

(c) x is at 2 twice, and -2 twice.

y is at 2 once, and is never negative.

The graph that fits is IV.

(d) x is at 2 and stays there for a period of time.

y is at -2 and stays there for a period of time.

The graph that fits is II.
