That derivative is - 1 / (x + 1)²
y = x + 1 1 + 2 = ( x + 1 ) − 1 + 2 y ′ = [ ( x + 1 ) − 1 + 2 ] ′ = − ( x + 1 ) − 1 − 1 = − ( x + 1 ) − 2 = − ( x + 1 ) 2 1
The derivative of the function y = x + 1 1 + 2 is − ( x + 1 ) 2 1 . This is obtained by applying the quotient rule to the first term and recognizing that the derivative of a constant is zero. Therefore, the final answer is − ( x + 1 ) 2 1 .
