Question

let c be the function whose graph is given to the right. this graph represents the cost c of using m anytime cell - phone minutes in a month for a five - person family plan. (c) determine c(3000). interpret this value. c(3000)=330 now interpret the value of c(3000). choose the correct interpretation below. a. the value of c(3000) represents the monthly charge if 3000 minutes are used. b. the value of c(3000) represents the monthly charge if each person on the plan uses 3000 minutes. c. the value of c(3000) represents the minutes used that correspond to a monthly charge of $3000.

Explanation:

Step1: Recall function - interpretation concept

The function $C(m)$ represents the cost $C$ in dollars for $m$ minutes of cell - phone usage. When we find $C(3000)$, we substitute $m = 3000$ into the cost function.

Step2: Interpret the result

The value of $C(3000)$ gives the cost when the number of minutes used is 3000. In the context of the problem, it represents the monthly charge if 3000 minutes are used.

Answer:

A. The value of C(3000) represents the monthly charge if 3000 minutes are used.
