Question

{(1, 2), (1, 8), (3, 6), (4, 8)} is this a function

Answer 1

the given relation is not a Function.

Step-by-step explanation:

For a relation to be a function, No two input must have more than one output.

That means no two value of x must have more than one value of f(x).

For the given question;

`\mleft\{\mleft(1,2\mright),(1,8),(3,6),(4,8)\mright\}`

For the input of value 1, there are two outputs 2 and 8.

`\mleft(1,2\mright),and(1,8)`

Since there are more than one output for the input, it is not a function.

Therefore, the given relation is not a Function.
