Answer from: alarconanais07

Domain: 0 $\leq$ t $\leq$ 40 Range: 0 $\leq$ V(t) $\leq$ 200

Step-by-step explanation:

The domain is greater than or equal to 0 and less than or equal to 40 because in 40 months, she will lose all her money ($5 x 40months = $200) since she loses 5 dollars per month. Not to mention, time can't be negative in any situation. For the range, the value has to be greater than or equal to zero and less than or equal to 200 because she only has $200, the more time she spends using the phone, the more money she will lose over the course of the month( limiting her time). I hope this helps!

Domain: $0\leq t\leq 40$ ; Range: $0\leq V(t)\leq 200$

Step-by-step explanation:

The price of the cellphone was initially of $200. Each month, its price decreases by $5. Then, you have that for 200/5 = 40 month the price of the cellphone will be of $0.

The price of any object always will have a positive value. If V(t) is a function that describes the price of the cellphone in time t, with t in months, you have that the domain of the function is given by the total amount of months on which the cellphone has some price, that is, for:

$0\leq t\leq 40$

The range of the function is the price of the cellphone. Its initial price was $200 (maximum price) and its final price after 40 months is $0 (minimum price). Hence, the range of the function is:

$0\leq V(t)\leq 200$
