Statement best describes the relation (c,f)?

b

step-by-step explanation:

you have it right, no matter what value of either variable you input, farenheit or celsius, only one corresponding answer will be produced. this is a typical linear equation. not all functions pass through the origin since any linear relationship exhibited by the traditional y=mx+b, has the "constant" or b component which will move the line off the origin if it is positive or negative.

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
