Question

The value of f(0) , so that the function $f left parenthesis x right parenthesis equals fraction numerator square root of a squared minus a x plus x squared end root minus square root of a squared plus a x plus x squared end root over denominator square root of a plus x end root minus square root of a minus x end root end fraction$ becomes continuous for all $x$ is given by

$\sqrt{a}$
$- \sqrt{a}$
$a^{s 3 / 2}$
$- a^{3 / 2}$

The correct answer is: $negative square root of a$
