Question

NECESITO RESOLVER DERIVADA POR DEFINICION DE F(X)= X+1

                                                                                   ------

                                                                                   X-2

Answer 1

d/dx= (x-2 d/dx x+1-x+1 d/dx x-2)/(x-2)^2

d/dx= (x-2 d/dx x+ d/dx 1-x+1 d/dx x- d/dx 2)/(x-2)^(2 )
d/dx= (x-2 (1)+ (0)- x+1 (1)- (0))/(X-2)^2
d/dx= (x-3-x+1 )/(x-2)^2
d/dx= (-2)/(x-2)^2
