વિધેય $f : R \rightarrow  R$, $f(x) = \frac{{{{(x\, + \,1)}^4}}}{{{x^4} + \,1}}$ નો વિસ્તારગણ ...... છે 

A

[$0 , \infty$] 

B

[$0 , 16$]

C

[$0 , 8$]

D

[$0 , 32$]

Solution

Least values of $f(\mathrm{x})$ is obviously $'O'$

$\frac{x^{4}+1}{2} \geq\left(\frac{x+1}{2}\right)^{4} $ 

$\Rightarrow \frac{(x+1)^{4}}{x^{4}+1} \leq 8$
