An online streaming service that offers TV shows, documentaries, and movies charges an initial fee of $18.75 and an additional monthly membership fee of $4.25. The total cost, N(t), for a member after t months can be expressed with the function N(t) = 4.25t + 18.75. What is the range of the function in the context of the problem?

Respuesta :

The range of the function in the context of the problem is N(t) >= 18.75

How to determine the range?

The function is given as:

N(t) = 4.25t + 18.75

The value of t can only be 0 or more.

So, we have:

N(t) >= 4.25 * 0 + 18.75

Evaluate the product

N(t) >= 0 + 18.75

Evaluate the sum

N(t) >= 18.75

Hence, the range of the function in the context of the problem is N(t) >= 18.75
