The graph shows the temperature over a period of time of a chemical compound that is placed in a cold chamber. What is the domain of this function?

Graph showing a line segment that goes from ordered pairs 0, 20 to 35, negative 10

A.The domain is all real numbers 20 through negative 10.
B.The domain is all integers from 20 through negative 10.
C.The domain is all real numbers 0 through 35.
D.The domain is all integers from 0 through 35.

Answer 1

It's not B: I got it wrong xD

Explanation:

Answer 2

The correct option is C.

Explanation:

It is given that a line graph shows the temperature over a period of time of a chemical compound that is placed in a cold chamber.

Domain is the set of all possible inputs for which function is defined.

If a function defined from
`(x_1,y_1)` to
`(x_2,y_2)`, then the domain is

`Domain=[x_1,x_2]`

The end points of the line are (0,20) and (35,10). It means lines segment joining these two points. The domain of the function is

`Domain=[0,35]`

It means domain of the function is all real numbers 0 through 35. Option C is correct.
