DVD Video Rentals (Refer to Example 3.) The func- tion V computes the percent share of disc DVD rentals
accounted for by various companies. This function is
defined by V(R) = 37, V(N) = 30, and V(S) = 17,
where R is Redbox, N is Netflix, and S is rental stores.

(a) Write V as a set of ordered pairs.
(b) Give the domain and range of V.
T

Step-by-step explanation:

Given

Solving (a): Set of ordered pair

A function y = f(x) is represented as (x,y)

So, the ordered pair of V is:

Order the alphabets in increasing order

Solving (b): The domain and the range

In a function

The domain and the range are represented as:

So, we have:

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
