If a function f satisfies the rule f(-x) = f(x) for every member of x in its domain, then f is called an

even function. (Figure 19)

If a function f satisfies the rule f(-x) = f(x) for every member of x in its domain, then f is called an

even function. (Figure 19)

The geometric significance is that an even function is symmetric

with respect to the y-axis.

If f satisfies f(-x) = -f(x), then f is called an odd function.

(Figure 20)

If f satisfies f(-x) = -f(x), then f is called an odd function.

(Figure 20)

The graph of an odd function is symmetric about the origin.

Determine whether each of the following functions is even, odd, or neither.

Determine whether each of the following functions is even, odd, or neither.

The graph in figure 22 rises from A to B, falls from B to C, and rises again from C to D. The

function f is said to be increasing on the interval [a,b], decreases from [b,c], and increases

again from [c,d].
