For an even function, f(-x) = f(x) for all x. For an odd function, f(-x) = -f(x) for all x.
27 is an odd number.
In the same way that and odd plus and even is always odd. For example, 7*3 = (7+7) odd + odd = even , then add +7, apply rule that odd + even = odd and get that it equals 21.
The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
