Question

tell if f(x)=-x^2-5 is an even or odd function and describe its symmetry

Answer 1

even because degrees are 2 and 0 both even numbers

Answer 2

therefore symmetric wrt the y - axis

Answer 3

f(x) = f(-x) so its an even function

Answer 4

thankssssssssss !

Answer 5

easy to tell for a polynomial if even or odd. for odd ALL the degrees must be odd, like
\[f(x)=4x^5-x^3+2x\] for even ALL degrees must be even like in your example
