→ Find the domain and range of x+2/ Ix+2I ?

$\huge \tt{ \overbrace{ \underbrace{Answer :}}}$

$\tt{→ To \: find \: domain }$

$\tt{→ X - 2 \: is \: not \: equal \: to \: zero . }$

$\tt{→ So \: x \: is \: not \: equal \: to \: 2 . }$

$\tt{→ Domain \: is \: R- ( 2 ) \: its \: range \: is \: ( 1 , -1 . )}$

$\tt{→ Because \: it \: will \: give \: only \: 1 \: or \: -1 \: for}$

$\tt{any \: x \: belongs \: to \: R- ( 2 ) . }$

$\tt{→ We \: have \: function \: x - 2 / x - 21 .}$

$\tt{→ We \: know \: that \: |x - 21 | = + - ( x - 2 ) }$

$\tt{→ According \: to \: values \: of \: x .}$

$\tt{→ So , }$

$\tt{→ (x-2)/+-(x-2)=+-1}$
