Question

hey guys!

Here is my question for 50 points!

Which of the following set of pairs represents 'y' as a function of 'x'

A) (2,5) , (3,1) , (2,1) , (4,7)

B) (3,2) , (4,3) , (5,2) , (2,6)

C) (1,3) , (3,5) , (2,5) , (1,6)

D) (4,7) , (4,6) , (4,4) , (4,1)

The answer would really help me!

Answer 1

Answer : B)

(3,2) (4,3),(5,2),(2,6)


How?
Define Function :

A function is relation between a set of inputs
and a set of permissible outputs with the property that each input is related to exactly one output.

For example :

A function can have mapping like :
(1,2) (2,1) as
here for one input there is only one output I. e.
if x (independent variable) = 1 ., then
dependent variable is y = 2.

But it cant be like,
(1,2 ) (1,3)

Here. for one input (1), there are two outputs (2,3)
which contradicts the definition of function.

Now. In question
In options A, C, D , for one input there are two or more outputs.
But in B, for one input there is only one Output.
Thus, B is correctly mapped function.
