Best ResponseYou've already chosen the best response.0I could find f(1) , but can't find dy/dx f(1) , it's a derivative question.

Best ResponseYou've already chosen the best response.0Oh.. use implict deriavtion... and do the same thing by replacing f(0).

Best ResponseYou've already chosen the best response.0derivated case of equation is , 2*f(x)+2x*(dy/dx f(x))+(dy/dx f(1x))=6x^2+6x+4 , if we plug in 0 , we get f(0) and dy/dx f(0) , how can we get rid of these?

Best ResponseYou've already chosen the best response.0If you plug in 0, it will cancel the dy/dx f(x) and left you with 2*f(0) + dydxf(1x) = 4.. Now you try to figure out f(0) from the regular equation.
