Answer:
y = (x - 5)^2 + 16
Step-by-step explanation:
y (°F) Temperature
25
20
16
20
25
x (hours after midnight)
2
3
5
7
8
We can see in the picture below, the graph which appropiately displays the data points.
The function is
y = (x - 5)^2 + 16
We can easily check this represents the solution by eavluating each point
(2,25)
y = (2 - 5)^2 + 16 = 25
(3,20)
y = (3 - 5)^2 + 16 = 20
(5,16)
y = (5 - 5)^2 + 16 = 16
(7,20)
y = (7 - 5)^2 + 16 = 20
(8,25)
y = (8 - 5)^2 + 16 = 25
