3.C

At first it was (-a, f(-a)), and f(-a)=-f(a).

4.b=0, and the meaningful odd function at the origin must pass through the (0,0) point.

5.m=0, even functions cannot have odd powers of x.

6. y = x 2, others can also be y=|x|

7. Equality

Odd function adds and subtracts, and the result is odd function.

Even function addition and subtraction, the result is even function.

Or verify the relationship between f(x) and f(-x) according to the definition.

It must be noted that the domain of odd function even function must be symmetrical about the origin, which is easily overlooked.
