Best ResponseYou've already chosen the best response.1Well that depends really... The average value of its entire domain?

Best ResponseYou've already chosen the best response.1I can think of an even function which has a finite average value, and I can think of one that has an infinite one...

Best ResponseYou've already chosen the best response.1If you were talking about an odd function then it'd be easy...

Best ResponseYou've already chosen the best response.0What about an odd functon??

Best ResponseYou've already chosen the best response.1For an odd function it would be 0, since on the other side of the y axis you have negative values.

Best ResponseYou've already chosen the best response.0so the best ans is none...??

Best ResponseYou've already chosen the best response.1But to your previous question: For an odd function \(f\), we know that \(f(x)=f(x)\). As such, the average value (assuming \(f\) exists over all \(\mathbb R\)) is\[\lim_{a\rightarrow\infty}\frac{1}{2a}\int_{a}^af(x)dx=\lim_{a\rightarrow\infty}\frac{1}{2a}(\int_0^af(x)dx+\int_{a}^0f(x)dx))\]\[=\lim_{a\rightarrow\infty}\frac{1}{2a}(\int_0^af(x)dx+\int_{a}^0f(x)dx)\]Let \(u=x\)\[=\lim_{a\rightarrow\infty}\frac{1}{2a}(\int_0^af(x)dx\int_{0}^af(u)du)=0\]
