Whether the function is even or odd y = 5x ^ 7.

An even or odd function can be determined by the influence of the sign of the argument X on the value of the function Y. So, – a function that changes its value to the opposite when the sign of X changes is odd. In the case when the Y value does not change its value when the argument sign changes, the function is even.

Y (X) = 5 * X ^ 7;

Y (-X) = 5 * (-X) ^ 7 = -5 * X ^ 7 = -Y (X).

Answer: the function Y (X) = 5 * X ^ 7 is odd.
