8. Analyzing Graphs of Polynomial Functions
Sign In
A function f is an even function when f(- x)=f(x) for all x in its domain. A function f is an odd function when f(- x)=- f(x) for all x in its domain.
Odd
Before we begin, let's recall two important definitions.
h(x) | h(- x) | - h(x) |
---|---|---|
4 x^7 | - 4 x^7 | - 4 x^7 |
Since h(- x)=- h(x), the function h is an odd function.
