B = { 19, 15, 9, 11 } where f x^ h = 2 1 x - . Find the values of a and b.

Answer 1

QUESTION :
The following table represents a function from A= { 5, 6, 8, 10 } to
B = { 19, 15, 9, 11 } where f( x) = 2x -1 Find the values of a and b.

SOLUTION:
GIVEN :
A= { 5, 6, 8, 10 } to
B = { 19, 15, 9, 11 }

f( x) = 2x -1

f(5) = 5 ×2 -1 = 10 -1= 9
f(6) = 6 ×2 -1 = 12 -1= 11
f(8) = 8 × 2 -1 =16 -1= 15
f(10) = 10 × 2 -1 =20 -1= 19
Set of ordered pairs : {(5,9),(6,11),(8,15),(10,19)

Hence, the value of a = 9 & b = 15
