Question

$x$	$y$
$1,2$	a
$2$	b
$3$	c

This given table signifies

• A. Relation but not a Function
• B. Function but not a Relation
• C. Neither Relation nor Function
• D. Both Relation and Function

Answer 1

The correct option is A Relation but not a Function

In the table

$x$	$y$
$1,2$	a
$2$	b
$3$	c

This given table signifies that
For $x=1,y$ = a
for $x=2,y$ = a
For $x=2,y$ = b
and for $x=3,y$ = c
We can see that for $x=1$ and $2,y=a$ which is acceptable.

For a relation to be a function, each value in $x$ must correspond to a exactly one value in $y$.

Here at $x=2\Rightarrow y=a,b$
$\therefore$ the given relation is not a function.
