Question

If K={(x, y) x - y= 5), find the corresponding range of y for the domain (0, 2, 4).

O (-5, -3, -1)
O [0, 2, 4)
O (5,7,9)

Answer 1

Answer: ( -5, -3, -1 )

Explanation:

You are given the equation

x - y = 5

Rearrange the equation and make y the subject of formula

Y = x - 5

Where Y represent the range and x represent the domain

You are also given the domain to be : (0, 2, 4).

Substitute each value of the domain to get corresponding values for range y.

When x = 0,

Y = 0 - 5

Y = -5

When x = 2

Y = 2 - 5

Y = -3

When x = 4,

Y = 4 - 5

Y = -1

The corresponding range of y are :

( -5, -3, -1 )
