Match each table of data below with the most appropriate graph, and then briefly explain how you know the graph matches the data.

The temperature in an oven when cooking a roast.

Time (min)	Temperature ( $º\text{F}$ )
$0$	$70$
$5$	$200$
$15$	$300$
$30$	$325$
$60$	$325$
$120$	$325$
$180$	$325$

Hint (a):

The temperature rises immediately but as time passes it levels-off.

Answer (a):

Answer (b):

Graph 2

First quadrant, axes unlabeled, titled Graph 1: Increasing curve, opening downward, starting at 1 fourth way up, rising, then leveling out.

First quadrant, axes unlabeled, titled Graph 2: Increasing curve, starting at origin, opening upward, rising gradually, then rising rapidly.

First quadrant, axes unlabeled, titled Graph 3: Upside down V, starting about 1 fourth up, rising, & turning half way on the x, falling at the same rate.

First quadrant, axes unlabeled, titled Graph 4: Increasing curve, starting just above the origin, opening upward, rising gradually, at half way, rising very rapidly, turning to opening down, then leveling off.
