I don't understand how you determine whether a function is even, odd,or neither.
Here are my problems:
Determine whether the given function is even, odd, or neither.
8. f(x)=x^3-x^2
This is how I did it.
f(-x)=(-x^3)- (-x^2)= (-x)(-x)(-x) - (-x)(-x) = (-x^3) -(x^2)- I got that it was odd
9. f(x)=-4x^5+x^3 This is how I did it:
f(-x)=-4(-x^5) + (-x^3)=4x^5-x^3 - I got that it was neither.

8. Both answers are wrong. The #8 f(x) is neither even nor odd. It is the sum of an even term (x^2) and and odd term (x^3). The #9 f(x) is odd. It is the sum of two odd terms.
