Question

Let {A}={5,6,7,8}:B={ 11,4,7,-10,- 7,-9,-13 } and F={x, y }:y= 3 - 2x, x belongs to a,y belongs to b

Answer 1

Step-by-step explanation:

for the value of x the numbers are taken from set A only and y numbers from Set B

y = 3 - 2x

for x = 5

y = 3- 2X 5 = 3 - 10 = -7

(x, y) = (5, -7)

for x = 6

y = 3- 2X6 = 3-12 = -9

(x,y) = (6,-9)

for x = 7

y = 3 - 2X7 = 3 - 14 = -11

(x, y) = (7, -11) it will not be a member of set F, as -11 is not an element or member of set B

for x = 8

y = 3 - 2x8 = 3 - 16 = -13

(x, y) = (8, -13)

F = { (5,7), (6,-9), (8,-13)}

I hope it helps.
