Interpreting Graphs

A graph tells a story. Before you compute anything, you can read it — where the curve climbs, levels off, or falls, and where it peaks or bottoms out.

Relating a graph to an event: a rising segment means the quantity is growing, a falling segment means it's shrinking, and a flat segment means it's constant (unchanging) — not zero.
Key features: the intervals where a function is increasing, decreasing, or constant; where it is positive or negative; its maximum or minimum; and its intercepts.

The graph is given — your job is to interpret it. These are real, released Regents questions.
