average rate of change is just the slope from (0,f(0)) to (2,f(2))
basically, average rate of change=slope=
evalaute each
f(2)=4(2)^2=4(4)=16
f(0)=4(2)^0=4(1)=4
so average rate of change=
average rate of change is 6
Answer:
Top and bottom= 12cm2
front and back= 36cm2
left and right= 24cm2
Surface Area = 72 cm2
Step-by-step explanation:
Top and bottom= 2×(3×2)12cm2
Surface Area = 2×(3×2 + 3×6 + 2×6) = 72 cm2
