Answer:
The third option is correct.
The domain of the function is given by

The range of the function is given by

Step-by-step explanation:
Sara bought a cell phone for $200 and its value has decreased at rate of $5 per month.
V(t) is the value of the phone and t is the number of months.
The domain of the function is the possible values of the number of months t.
The domain of the function is given by

The range of the function is the values of V(t) that we get after substituting the possible values of the number of months t.
The range of the function is given by

When the number of months is t = 0 then the value of the function is maximum V(t) = 200
When the number of months is t = 40 then the value of the function is minimum V(t) = 0
Therefore, the third option is correct.
