For Questions 1 and 2 use the following graphs:

 Graph I Graph II Graph III Graph IV Graph V For which of the graphs from I) – V) above, if any, is there a value for $c$ in $(-4,6)$ where $f'(c) = \dfrac {f(6)-f(-4)}{6-(-4)}$?
Graph I) only Graph II) only Graph III) only Graph IV) only Graph V) only Graph III) and Graph IV) only Graph IV) and Graph V) only Graph I), Graph IV) and Graph V) only Graph III), Graph IV) and Graph V) only Graph I), Graph II), Graph IV), and Graph V) only Graph I), Graph III), Graph IV), and Graph V) only All five functions have a value for $c$ in $(-4,6)$ where $f'(c) = \dfrac {f(6)-f(-4)}{6-(-4)}$ None of the graphs have a value for $c$ in $(-4,6)$ where $f'(c) = \dfrac {f(6)-f(-4)}{6-(-4)}$
For which of the graphs from I) – V) above, if any, is continuous over $[-4,6]$, differentiable over $(-4,6)$, AND there is a value for $c$ in $(-4,6)$ where $f'(c) = \dfrac {f(6)-f(-4)}{6-(-4)}$?

For the graph of $y = f(x)$ below, identify a value for $c$, if any, from the interval $(1,9)$ where $f'(c)=\dfrac {f(9)-f(1)}{9-1}$.
$c=-4$ $c=-3$ $c=0$ $c=3$ $c=5$ $c=7$ No values for $c$ exist where $f'(c)=\dfrac {f(9)-f(1)}{9-1}$
Two police cars are stationed 1.9 miles apart on a highway that has a speed limit of 55 miles per hour. A red sports car passes in front of the first police car and is clocked at 55 miles per hour. 0.033 hours later (2 minutes), the red sports car passes in front of the second police car and is clocked at 54 miles per hour. Did the car exceed the speed limit at some time during the 0.033 hours?
