Please show work :) thannk you
(5 points) Given the function r(t) = 6− 24/ t and the values t = 6,t = 12.
(a) Determine the net change between the given values.
(b) Determine the average rate of change between the values
a
Net change = r(12) - r(6) =
[ 6 - 24/12] - [ 6 - 24/6] =
[6 - 2 ] - [ 6 - 4] =
4 - 2 =
2
b
Avg change = [ r(12) - r(6) / [ 12 - 6] = 2 / [ 12 - 6 ] = 2 / 6 = 1 / 3
