Question

What is the average value of the function f(x)=[4(x^2+1)]/x^2 on the interval [1,3]?

Answer 1

i think its integral divided by the length of interval

Answer 2

yeah but do i need to find the derivative or just use tht??

Answer 3

so you integrate f(x) from 1 to3, then divde by 2

Answer 4

is tht the derivative??

Answer 5

no, you need to integrate, not differentiate

Answer 6

wait, let me double check

Answer 7

ok thx

Answer 8

yep, you integrate, not differentiate f(x)

Answer 9

oh okay, so even if it's just a normal function you would still integrate it?
