Which of the following is an odd function? f(x) = 3x2 + x f(x) = 4x3 + 7 f(x) = 5x2 + 9 f(x) = 6x3 + 2x

Odd function by definition has the property:

Thus, we can immediately rule out all even powers of x. Now, we are left with the second and the last option. We can rule out the second option too because and thus,

Now, the last option is:
