Answer:
Domain of function is whole numbers from 0 to 10.
Step-by-step explanation:
Given the graph of function represents the tickets sold vs cost.
A movie theater sells up to 10 tickets at a time online. we have to find the domain of the graph.
As shown in graph number of tickets sold 0 to 10 and also number of tickets are always positive and a whole number. It can never be negative or in fraction form.
Hence, the value of x is positive whole number.
The domain of function is the complete set of possible values of x i.e of independent variable.
⇒ Domain of function is whole numbers from 0 to 10.
Option 4 is correct.
