Best ResponseYou've already chosen the best response.1function is f(x) = sqrt{14x} <replace x with x+h to find f(x+h)

Best ResponseYou've already chosen the best response.1formula is \[\large\rm \frac{ f(\color{ReD}{x+h}) f(x) }{ h }\]

Best ResponseYou've already chosen the best response.0So square root 14(x+h)

Best ResponseYou've already chosen the best response.0Im at.. square root 14 (x+hx) over h(square root x+h + square root x)

Best ResponseYou've already chosen the best response.1yes right so \[\huge\rm \frac{ \sqrt{14(x+h)}  \sqrt{14x} }{ h }\]

Best ResponseYou've already chosen the best response.1eh eh what nope you can't combine both sqrts

Best ResponseYou've already chosen the best response.1hmm how did you get square root x+h + square root x) at the denominator ?

Best ResponseYou've already chosen the best response.0Final answer> square root 14 over square root x+h + square root x

Best ResponseYou've already chosen the best response.1sqrt{14(x+h) } can be written as sqrt{14} sqrt{x+h) so \[\frac{ \sqrt{14}\sqrt{x+h} \sqrt{14}\sqrt{x}}{ h }\] sqrt 14 is common so you can take it out

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ \sqrt{14} }{ \sqrt{x+h}+\sqrt{x}}\] is this ur final answer ?

Best ResponseYou've already chosen the best response.0Yes and its correct.

Best ResponseYou've already chosen the best response.1ahh i see so you have to multiply top and bottom with the conjugate of the numerator

Best ResponseYou've already chosen the best response.1sqrt{14(x+h) } can be written as sqrt{14} sqrt{x+h) so \[\huge\rm \frac{ \sqrt{14}\sqrt{x+h} \sqrt{14}\sqrt{x}}{ h }\] sqrt 14 is common so you can take it out did you understand that step ?

Best ResponseYou've already chosen the best response.0Yeah it gets moved to the front  square root 14 ( square root x+h)  square root x over h ... That was the second step
