In case of graph, for domain we consider all the x values.

Domain is all input values for which we get a real output or all possible x values for which we get real y values.

here from the graph we can see the possible x values are all real numbers from 0 to 8.

So option A is correct.

Hello!

As you can see, this graph goes through x-values 0-8. We could use all real numbers as time could be measured in small fractions.

Therefore, our answer is A.

I hope this helps!
