Graphs are a great way to see patterns in math, especially when we talk about even and odd functions. Let’s break it down:

1. Even Functions: These functions look the same on both sides of the $y$-axis. For instance, if you look at the graph of $f(x) = x^2$, you’ll notice it’s identical on the left and right sides of the $y$-axis. When you change $x$ to $-x$, the output stays the same: $f(-x) = f(x)$. This symmetry is easy to spot just by looking at the graph.

2. Odd Functions: On the other hand, odd functions are symmetric around the origin. A good example is $f(x) = x^3$. Here, if you switch $x$ with $-x$, the output also changes sign: $f(-x) = -f(x)$. When you graph these, they appear as if you can flip them over 180 degrees around the origin and they’ll look the same.

3. Quick Checks: By drawing or looking at these graphs, you can easily tell if a function is even, odd, or neither. This helps you understand symmetry in math better!
