To determine if a piecewise function is even or odd, evaluate the function at both x and -x across its defined intervals. For the function F(x) given, F(-5) equals 0 and F(5) equals 8, indicating that F(x) is neither even nor odd since F(-x) does not equal F(x) or -F(x). The key is to analyze the function values in relation to their symmetry about the y-axis. Understanding the behavior of each piece in its respective interval is crucial for this analysis. Thus, the function's classification depends on these evaluations across its defined intervals.

I know what it means by by even, or odd, function. i also know what it means graphically.

My question is how to find a whether a function is even, or odd? if the function is defined in three intervals or more than three intervals.

Consider a function F(x) defined in the interval (a,d)

F(x)= [ p(x) where x belong to the interval (a, b);
q(x) where x belong to the interval (b, c);
r(x) where x belong to the interval (c, d); ]

The particular problem I'm faced with is:

F(x)= [ p(x)=0 where x belong to the interval (-8,0);
q(x)=4 where x belong to the interval (0,4);
r(x)=8 where x belong to the interval (4,8); ]

You say you "know what it means by even, or odd, function" so just apply that. In particular F(-5)= 0. F(5)= 8.

That tells you all you need to know.
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
