D, E, and C all look odd to me because they are not symmetrical. HELP
+9481 E is not symmetric about the y-axis, but it is symmetric about the origin.
So E is an odd function.
+9481 Yes...and also you can look at it like this..if f(-x) = -f(x) then it is odd.
On E, it looks like (2, 8) might be a point...
If it is odd, f(-2) must equal - f(2) = - 8
Does f(-2) = -8 ? Is (-2, -8) a point? Yes...and it will be like this for all x values, so it is odd.
