Free Response
Reminder: For each of the following problems, you must show all of your work
to earn full credit. You may not use tools such as L’hopital’s rule or other
applicable techniques which you may have learned elsewhere. You may only use
techniques discussed in class up to and including chapter 2.4.
1. (11 Pts) Consider the quadratic function f(x)=ax2+bx +c.Determinethevalues
of the constants a,b,andcif f(1) = 8, f′(1) = 5, and f′′(1) = 6.
2
2. (11 Pts) Use the limit definition of the derivative to compute f′(x)iff(x)=√x
(No other method will be accepted, regardless of whether you obtain the
correct derivative.)
