I don't quiet understand the concept of even, odd and neither functions.
Test to see if each function below is even, odd or neither.
What makes a function NEITHER?
I somewhat grasp the odd and even idea (somewhat) but what actually makes it neither?
(1) f(x) = 2x + 5
(2) y = x^3 - 7
(3) h(x) = -5x^5 + 3x^4
