Given
(a) to (d)
Required
Which is not a function
A relation is represented as:
For the relation t be a relation, then:
where 
This means that none of the x values must be related.
The first relation has 3 repeated as its value of . Hence, (a) is a relation
Answer:
K(F) = 5/9 (F - 32) + 273.15
K(F)=298.15k
Step-by-step explanation:
C(F) =5/9 (F - 32) is used to convert temperature from Fahrenheit (F) to Celsius (C).
C(F) =5/9 (F - 32)
The function K(C)= C + 273.15 is used to convert temperature from Celsius (C) to the Kelvin (K) scale.
K(C)= C + 273.15
K(c) - 273= C
Equating both values of C
K(F) - 273.15=5/9 (F - 32)
K(F) = 5/9 (F - 32) + 273.15
If F = 77°F
K(F) = 5/9 (F - 32) + 273.15
K(F) = 5/9(77-32) + 273.15
K(F) = 5/9(45) +273.15
K(F) = 25+273.15
K(F)=298.15k
