math(rate of change)
posted by ash .
find the average rate of change
f(x)=x^2 + 2x between x=0 and x=6
can anyone please help me explain why the answer is 8?
thank you!

I assume you are not a calculus student.
avg rate= (f(6)f(0))/(60)=(480)/6=8 
nope im not :( and my teacher doesn't explain well...thank you! i've been trying to figure out how to come up with the asnwer but gosh i couldn't thank you again!

how did it become 48?

f(6) = 6^2 + 2(6) = 36+12 = 48

{{{(f(6)  f(0))/(60) = (6^2 + 2*6  0^2  2*0)/6 = 48/6 = 8}}}
