Find and simplify the derivative of the following function. X f(x) = = x+1 Which of the following shows how to find the derivative of f(x)? O A . f'(x ) = x ( x ) ( x + 1 ) + ( * ) x ( * + 1 ) / O B. F'( x ) = x ( x ) ( x ) + ( x + 1 ) ax ( * + 1 ) ( x + 1 ) x ( * ) - ( * ) ax ( * + 1 ) O C. F(x)= (x+ 1) (x ) x ( * + 1 ) - ( * + 1 ) x ( * ) OD. F' ( X) = (x + 1)2 x The derivative of f(x) = x + 1
