Step-by-step explanation:

Your answer is in attachment

Answer 2

Answer:  $\frac{1}{-e^{-1} }$.

Step-by-step explanation:

• To solve this we need to know the concept od differentiability of a function.
• The solution is in the attachment.
• Hence,radius of curvature at y maximum is $\frac{1}{-e^{-1} }$.
