Answer 1

Answer:

Correct choice is D). -4.

Step-by-step explanation:

Given the following relation is a function where the relation is :

{(6,3),(-4,1),(8,-5),(x,1)}

Now we need to decide about which of the following cannot be a value for x.

Where given choices are:

A). 3

B). 1

C). -5

D). -4

E). 4

We know that a relation is called function if doesn't contains repeated values in domain or doesn't have repeated x-values.

In given relation, {(6,3),(-4,1),(8,-5),(x,1)}, we see that x-values are 6, -4 and 8.

So to prevent repetition, x can't be any of 6, -4 and 8.

Hence correct choice is D). -4.
