I live in Jacksonville and want to head down to see the Dec 6th launch. I was told that it's pricey to go watch the launch inside the space center but that you can go just south of cape canaveral and watch it from the beach. I'm not sure where though. Could someone tell me where is a good place...maybe what exit off of 95? Thanks

QUESTION:
How would you arrange the steps in order in a continuous, twice differentiable function when finding its inflection point?

THE CHOICES IN RANDOM ORDER:

A = evaluate the function at the points where the second derivate is zero
B = analyze the sign changes of the second derivative
C = find the zeors of the second derivative
D = find the second derivative
E = find the first derivative

Whats the proper order A through E?

Thanks!
