Question

Choose the correct ordered pairs represented in the table. The following table gives per unit cost for furniture and shows selling prices. The numbers represent hundreds of dollars.
C 1 2 3 4 5
F(c) 4 6 8 10 12

Answer 1

Given the table

C :     1, 2, 3,   4,   5

F(C) : 4, 6, 8, 10, 12

Usually, the independent variable is represented by the x-value while the dependent variable (or the function) is represented by the y-value.

Thus the points represented by the table are:

(1, 4), (2, 6), (3, 8), (4, 10) and (5, 15).
