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.
(a) determine c(0). interpret this value.
c(0)=□
...

Explanation:

Step1: Identify the value of \(C(0)\)

From the graph, when \(m = 0\) (the number of minutes is \(0\)), the corresponding \(C\) - value (cost) is \(89\).

Step2: Interpret the value

The function \(C(m)\) gives the cost of using \(m\) anytime cell - phone minutes. When \(m = 0\) (no minutes used), \(C(0)=89\) represents the fixed cost (base cost) of the five - person family plan, i.e., the cost even when no minutes are used.

Answer:

\(C(0) = 89\). This value represents the fixed cost (base cost) of the five - person family plan (the cost when no anytime cell - phone minutes are used).
