f(x)=4 x^{3}+3 x^{2}+3 x+4

, then

x^{3} f\left(\frac{1}{x}\right)

View answer and explanation

Correct option: D

f(x)

Option D (

f(x)

) is correct because when you compute

x^{3} f(\frac{{1}}{{x}})

, it simplifies back to the original function

f(x)

Practice All Chapter MCQs →

f:(-\infty, 2] \longrightarrow(-\infty, 4]

f(x)=x(4-x)

f^{-1}(x)

g(f(x))=|\sin x|

f(g(x))=(\sin \sqrt{x})^2

f:\left( {2,\;3} \right) \to \left( {0,\;1} \right)

f\left( x \right) = x - \left[ x \right]

{f^{ - 1}}\left( x \right)

f: R \rightarrow R

f(x)=x^4

f(x)=(x+1)^2-1(x \geq-1)

S=\left\{x: f(x)=f^{-1}(x)\right\}
