Answer:
The correct option is C.
Step-by-step 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 [tex](x_1,y_1)[/tex] to [tex](x_2,y_2)[/tex], then the domain is
[tex]Domain=[x_1,x_2][/tex]
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
[tex]Domain=[0,35][/tex]
It means domain of the function is all real numbers 0 through 35. Option C is correct.
