Question

Creating a function machine can be time consuming and awkward. The

Answer 1

The ordered pairs for :

(a) Y = 9-4x are (-2,17), (5,-11) ,(2/3,19/3) and (0.75,6).

(b) Y = 1/x are (-2.-1/2), (5,1/5), (2/3,3/2) and (0.75,1.33)

We are given two functions for which corresponding y-values need to be found for the given x-values so that ordered pairs of the form (x, y) can be formed.

Consider the function Y = 9-4x.

When x = -2, y = 9-(4 x -2) = 17

When x = 5, y = 9-(4 x 5) = -11

When x = 2/3, y = 9-(4 x 2/3) = 9-(8/3) = 19/3

When x = 0.75, y = 9-(4 x 0.75) = 6

So the ordered pairs are: (-2,17), (5,-11) ,(2/3,19/3) and (0.75,6).

Consider the function Y = 1/x

When x = -2, y = 1/-2 = -1/2

When x = 5, y = 1/5

When x = 2/3, y = 1/(2/3) = 3/2

When x = 0.75, y = 1/0.75 = 1.33

So the ordered pairs are: (-2.-1/2), (5,1/5), (2/3,3/2) and (0.75,1.33)
