SUMMARY

The function x^3 - x + 1 is classified as neither even nor odd. An even function satisfies the condition f(-x) = f(x), while an odd function meets the requirement f(-x) = -f(x). Upon substituting -x into the function, it does not fulfill either condition. Additionally, the polynomial's symmetry characteristics confirm that it does not exhibit the necessary properties of even or odd functions.

Is the function x^3 - x + 1 even, odd, or neither? When I graphed this, it looked like it was symmetric about the origin, so I thought that it might be an odd function. Either that or it is neither?

A function is even if:

f(-x) = f(x)

A function is odd if:

f(-x) = -f(x)

So to figure out if it's even of odd, plug in -x in place of x and compare it to the original.

Look at graph

Also I believe that odd fuctions are rotationaly symetric while even fuctions are symetic on the vertical line. (When a graph is fliped horizontally over it)
 
f(0) isn' 0 so it certainly isn't odd, and clearly it isn't even.

hint: a polynomial in x is even (odd) iff the powers of x are all even (odd)
