Best ResponseYou've already chosen the best response.0its sqrt(x+4+h) + sqrt(x) you cannot simplify anymore, but this is usually used to find the derivative of f(x).

Best ResponseYou've already chosen the best response.0Yes. Over it's x+4 all under the squareroot.

Best ResponseYou've already chosen the best response.2k so f(x+h)=sqrt(x+h+4) therefore we have f(x+h)+f(x)=sqrt(x+h+4)+sqrt(x+4)

Best ResponseYou've already chosen the best response.0So it's\[\sqrt{x+h+4}\] + \[\sqrt{x+4}\]
