Here is the graph of a function.
Select the equation for the function represented by the graph.
Function on coordinate plane, origin O. X axis from negative 6 to 4 by 2’s. Y axis from negative 6 to 4 by 2’s. Line starts at negative 6 comma 1, decreases until 0 comma negative 5, increases passing through 2 comma negative 3 and 5 comma 0.

The temperature was recorded at several times during the day. Function
Pick two consecutive points, and connect them with a line segment.
Estimate the slope of that line. Explain what that estimated value means in this situation.
Discrete graph of temperature over time, coordinate plane, origin O. Horizontal axis scale 0 to 25 by 5’s, labeled “time of day”. Vertical axis scale 30 to 70 by 10’s, labeled “temperature (Fahrenheit)”. The points are near (1 comma 42), (2 comma 40), (3 comma 39), (4 comma 38), (5 comma 36), (6 comma 36), (7 comma 37), (8 comma 41), (9 comma 47), (10 comma 51), (11 comma 55), (12 comma 61), (13 comma 64), (14 comma 66), (15 comma 68), (16 comma 69), ( 17 comma 69 point 3), (18 comma 69), (19 comma 66), (20 comma 63), (21 comma 57), (22 comma 50), (23 comma 41) and (24 comma 32).

Here are two graphs representing functions
Identify at least two values of
Parabolas f and g on coordinate plane, origin O. X axis from negative 5 to 5 by 1’s. Y axis from 0 to 5 by 20’s. Function F opens upwards with vertex at the origin, passes through negative 5 comma 25 and 5 comma 25. Function G opens downwards with vertex at 1 comma 15, passes near negative 3 comma 0 and 5 comma 0. The parabolas intersect near negative 2 point 25 comma 5 and 3 point 25 comma 10.
