  • D
    $(-5.25,4.75)$

Answer

Correct option: A.
$(4.75,5.25)$
$(4.75,5.25)$
$\text { Modulus form } $ $=|x-a|<8 $
                             $=|x-5|<0.25 $
                          $a  =5, \delta=0.25$

$\text { Interval form }$  $=(a-\delta, a+\delta)$
                            $ =(5-0.25,5+0.25)$
                            $ =(4.75,5.25)$
