Question 939090
{{{ c(s) =(3(s)^3-(s)^2+5(s))/((s)^3+10) }}}
average rate of change from 0.75 to 1.5 seconds 
{{{(c(1.5) - c(.75))/(1.5-.75) =  (1.1495 - .4273 )/(1.5-.75) }}}
Re TY 
Used Graphing Calculator to Determine c(1.5) = 1.1495
Note Below for c'(1.5)
.... 
instantaneous rate of change at 1.5 seconds.
c'(1.5)= 1.0834
