Considering it's definition, an odd function is represented by the second function given.
What defines an odd function?
An odd function is defined by the following rule:
f(x) = -f(x).
This means that for example:
- If f(1) = -1, then f(-1) = 1.
- If f(2) = 0, then f(-2) = 0.
- If f(3) = 5, then f(-3) = -5.
The only graph for which this relation is valid in this problem is the second graph, from which all examples off the numeric values were taken, hence an odd function is represented by the second function given.
