I can’t be sure because some of the expressions are garbled. Could you retype the functions exactly (use ^ for powers, e.g. x^4)?
Meanwhile, here’s how to tell — and what I can read from your text:
- Test f(-x) = f(x). For polynomials this means every power of x must be even (constants allowed).
- From what I can parse:
- T(x) = -x^8 + 726 is even (x^8 and the constant are even powers).
- f(x) = 8x - 3 is not even (8x is odd).
- s(x) = -9x^10 + 5x^4 - 12x is not even because of the -12x term.
If you paste the functions again clearly (e.g. f(x)=38x^2, g(x)=10x^6+1, etc.), I’ll mark exactly which are even.
