c.option is correct pls mark me as BRAINLIEST

Answer 2

Answer:

$Correct option is</p><p></p><p>C</p><p></p><p>[0,21)</p><p></p><p>The maximum value of fractional part of x tends to 1 but is never 1 actually. Its lowest value is 0 though.</p><p></p><p></p><p>f′(x)=(1+{x})21.</p><p></p><p></p><p>This is always positive. So f(x) is an increasing function.</p><p></p><p></p><p>Hence minimum value of the function is at x=0. f(x)=0</p><p></p><p></p><p>Maximum value of f(x) is as {x} tends to 1. The limiting value of the fuction is 21 but it is never actually attained by the function</p><p></p><p>$
