Question

Find the value of the expression $x$ for the given values of $x:$
$x=1,5,-6,\frac{3}{7}$

• A. $1,5,-6,\frac{3}{7}$
• B. $1,4,-6,\frac{3}{7}$
• C. $1,5,6,\frac{3}{7}$
• D. $2,5,-6,\frac{3}{7}$

Answer 1

The correct option is A $1,5,-6,\frac{3}{7}$

$x=\{1,5,-6,\frac{3}{7}\}$
Expression : $x$
When we take $x=1,$ output $x=1$
When we take $x=5,$ output $x=5$
When we take $x=-6,$ output $x=-6$
When we take $x=\frac{3}{7},$ output $x=\frac{3}{7}$
So,

$x$	$\to$	$x$
$1$	$\to$	$1$
$5$	$\to$	$5$
$-6$	$\to$	$-6$
$\frac{3}{7}$	$\to$	$\frac{3}{7}$

The output is always $x$.
