Provide an appropriate response.Does the curve y = (x + 3)3 have any horizontal tangents? If so, where? Give reasons for your answer.
What will be an ideal response?
The curve y = (x + 3)3 has a horizontal tangent at x = -3. The derivative of the curve is 
which equals zero at x = -3. A curve has a horizontal tangent wherever its derivative equals zero.
