Hi, I have a test on pre calc topics on Monday in my Calc class.
I am reviewing odd and even functions right now.
Here is the problem: True or False: The function f(x)= x^-3 is an odd function.
I have true and this is what i did to prove it:
(-x)^-3 = -x since it equals -x it's odd right?
But then I graphed it on my graphing calculator and it did not look right O_o... am I doing something wrong? Can i be neither?
