Homework Statement
Consider the following function of variable r, for r greater or equal to 0.
y(r)=(r^2-8r)exp(-r)
1. Find the value of the first derivative at r=8.00
2. Find the value of the second derivative at r=8.00
3. Find the value of r where y takes its meinimum value in the r is greater or equal to 0 interval
4. Find the value of r where y takes its maximum value in the r is greater or equal to 0 interval
Please explain how you do it too! I am so lost :(
