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

Answer 1

The correct option is C Both Relation and a function

$x$	$y$
$1$	$3$
$2$	$4$
$3$	$6$
$4$	$5$
$5$	$7$

The above information signifies that

For $x=1,y=3$
for $x=2,y=4$
For $x=3,y=6$
For $x=4,y=5$
and for $x=5,y=7$

For every value of $x$ there is only one value in $y$ that is associated with it.

For a relation to be a function, each and every value in $x$ must correspond to a different value in $y$.
$\therefore$ The given information is a relation as well as the function.
