Answer:
A
Explanation:
The domain of a graph is the span of x-values (or t-values in this case) it covers.
From the graph, we can see that the graph stretches from t=0 to t=14.
Also, note that since the endpoints are closed circles, we will include them within our domain.
Therefore, our domain is all values greater than or equal to 0 and less than or equal to 14.
In set notation, this is:
So, our answer is A
