(a) Find the ( x ,y ) coordinates of the local minimum y (circled on the graph) (b) Determine the coeﬃcients A , B , and C of the secondorder polynomial A + B ( xx ) + C ( xx ) 2 which can best approximate the function y around y . 3. Consider a string wrapped around a spool, which is rolling and unwinding on a table. The speed at which the spool rolls on the table ( A m/s, in meters / second) is equal to the total length of string ( A m, in meters) that has been unwound on the table. At T = 0, the length of string unwound on the table is L = 1 m. Find the length of string L on the table as a function of time T . 40 20 10 5 y = 8 ln(x) + (x  5) 2 1...
