anonymous · Answer

[f(t2)-f(t1)]/[t2-t1]

anonymous · Answer

would that be referring to f(3)-f(9)/(9-3) ??

anonymous · Answer

Close but switch f(3) and f(9) around

anonymous · Answer

ahh okay

so f(9)-f(3) 
   _________
     (3-9)

= 36-12
  ________
        6

=24/6 = 4 ?

jim_thompson5910 · Answer

it should be 

$$\Large \frac{f(9) - f(3)}{9-3}$$

but the answer of 4 is correct
