(b) Determine the average rate of change between the given values of the variable. Need Help? Endi. 3. O-12 points SAlgTrig4 2.4.019 M A function is given

Explanation / Answer

1) f(x) = 6x - 9

x = 2 , x = 3

f(3) = 6(3) - 9 = 9

f(2) = 6(2) -9 = 3

net change = f(3) - f(2)

net change = 6

b) avearage rate of change = 6/(3-2) = 6

2)  

h(t) = 2t^2 - t

t = 3 , t = 8

h(8) = 2(8)^2 - 8 = 120

h(3) = 2(3)^2 - 3 = 15

net change = 120 - 15 = 105

average rate of change = 105 / 5 = 21
