Question

A sprinter ran a race in 11 seconds. What is the domain of this graph?

Answer 1

Domain is defined as the all possible values of the variable x for which the function is defined.

Now, for the given graph the x-axis represents the time in seconds.

So, we need to find all the possible values of time for which the distance is covered or for which the function is defined.

Given that : The sprinter ran a race in 11 seconds.

And the initial time is 0 seconds

So, The value of t lies between 0 to 11

Thus, Domain : All real numbers 0 to 11
