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!
Answered by bobpursley
I assume you are not a calculus student.

avg rate= (f(6)-f(0))/(6-0)=(48-0)/6=8

Answered by ASH
how did it become 48?
Answered by Damon
f(6) = 6^2 + 2(6) = 36+12 = 48
Answered by bianca
{{{(f(6) - f(0))/(6-0) = (6^2 + 2*6 - 0^2 - 2*0)/6 = 48/6 = 8}}}
