Question

A cell phone company charges an initial price of $500 for a new phone and then $60 each month after the purchase. if c (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function? (2 points) r: (0, 500) r: (60, 560) r: ℠r: (−[infinity], [infinity])

Answer 1

The range of the rational function c(t) is all real numbers greater than or equal to 0.

Step-by-step explanation:

The range of the rational function c(t) that represents the average monthly cost of owning the cell phone can be determined by considering the possible values of t. Since t represents time in months, it can take on any non-negative value. However, the average monthly cost can never be negative, so the range of the function is all real numbers greater than or equal to 0. Therefore, the correct range of the function is r: [0, ∞).
