Final answer:
The question involves discussing points on a linear function other than the origin and understanding properties of functions such as horizontal lines and odd functions in different contexts.
Step-by-step explanation:
The question refers to a function u(x) = (6/5)x, which appears to be a linear function, and the ask is to discuss a point on this function other than the origin. Generally, for a linear function of the form f(x) = mx + b, any point (x, f(x)) on the graph where x is not zero will satisfy the inquiry.
For a horizontal line function f(x) = 20 for 0 ≤ x ≤ 20, the graph will show a constant value of 20 for all x in the given interval. The area under such a function between two points would represent the probability for uniform distributions in probability theory.
An odd function like xe-x² is one where f(-x) = -f(x). The integral of an odd function over all space is zero, which means the total area above the x-axis is canceled by the area below it.
