Answer :

EXPLANATION:

-The points of the independent variable that represent the domain of a function on a graph are always located on the x axis.

-The domain of a function is the range of values ​​of x for which f (x) exists, that is, the values ​​of x, for which f (x) has a result.

In the graph corresponds to the independent variable of time that corresponds to the real numbers on the positive axis between 0 and 40

NOTE:

"The domain is the range of values ​​of x, for which the function is drawn above. As we can see, from 0 to 40, the function is drawn. At no other value of x more"
