Even and odd functions both have symmetry; However, they don't have the same type of symmetry. Even functions have vertical symmetry or symmetry at the Y-axis. This can be represented by function f(-x)= f(x). Odd functions have symmetry at the origin, this type of function is written like f(-x)=-f(x). You can tell if a function is even by folding the graph in half, if the graph is the same on both side it's even. The same is not true for odd functions. You can create a table and if the y-coordinates are inverse of each other then it is an odd function. There isn't a family of functions that are always even or odd; although, some families are most of the time even and others most of the time odd. For example, squared functions are more often than not even. After this activity is still a little confused on how to determine if a function is odd mathematically
