Even: functions where the left half of the plane is a mirror image of the right half
Ex. f(x)= x^2
Odd: functions where the left half of the plane is a mirror image of the right half, but its upside down across from the other
Ex. f(x)= x^3
Simply: f(x) is even if f(x)= f(-x) and is odd if f(-x)= -f(x)
not just upside down though, it can be flipped around any other way. pretend its like a twister arrow. it spins on the origin, but its still the same image. ?? ahh, idk......
ReplyDeletemy analogies SUCK, but we have to comment. haha, im probably wrong anyhow
(its a picture i was trying to figure out)

Yes, but this was pretty much defined for you in my links. YOUR task was to explain how f(-x)=-f(x) is the same thing as being symmetric about the origin, etc. Explain the actual symbols f(-x)=-f(x)
