Graphs of functions !!
I need to determine if these are odd or even?
even if f(-x) = f(x)
odd if f(-x) = -f(x)
even if all powers are even
odd if all powers are odd
remember that 0 is an even power
So These Are all even?!
Sorry I'm still kind of lost..
come on. can't tell even and odd numbers?!?!?
x^5-x = x^5 - x^1
5 and 1 are both odd, so f(x) is odd
5 = 5x^0
0 is an even power, so f(x) is even
x^4 + 2x^3
4 is even, 3 is odd, so f(x) is neither even nor odd.
