@adosa  Hi,

$\huge \color{red}{\text{Welcome to Open Study}}\ddot\smile$

are you sure you need,  lim[x:4,f(x)] ??
because as per your question, you are given  lim[x:4,f(x)]=4

anonymous · Answer

yes

anonymous · Answer

suppose lim[x:4,f(x)=4] and lim[x:4,g(x)= -2], find, 
lim[x:4,xf(x)]

hartnn · Answer

okk, so you need 
$\lim \limits_{x \rightarrow 4}x f(x)$

anonymous · Answer

yes

hartnn · Answer

from $\lim \limits_ {x\rightarrow 4}f(x)=4 , \  \implies f(4)=4$

hartnn · Answer

so, $\lim \limits_{x \rightarrow 4}x f(x)= 4 f(4)=.... ?$

anonymous · Answer

suppose lim[x:4,f(x)=4] and lim[x:4,g(x)= -2], find, 
lim[x:4,g(x)/f(x)-1]

hartnn · Answer

did you get the answer to lim[x:4,xf(x)] ??

anonymous · Answer

4 right?

hartnn · Answer

no... 4 f(4) = 4*4 =16

anonymous · Answer

ok

thanks
