A function is given. Determine the average rate of change of the function between the given values of the variable.

Question

f(t) =
6/t
; t = a, t = a + h

Answer 1

f(t)=6/t
t1=a, t2=a+h
average rate of change
= Δf(t)/Δt
=(f(a+h)-f(a))/(a+h-a)
=(6/(a+h)-6/a))/(h)
=(6/h)(1/(a+h)-1/a)
...
simplify to get final answer.
