Answer:

A horizontal line is an example of a functional relationship.

All functions have an independent variable.

All functions have a dependent variable (At least).

Step-by-step explanation:

By description, a relation is a purpose if each input condition has one and only one output value.

A function has at least a secondary variable and an autonomous variable. For instance, given a function:

Y=X

The secondary variable is "y" and the autonomous variable is "x".

The Field of the role is the collection of potential input values and the Range is the collection of potential output values,

Vertical lines have an irregular slope. Since the value of "x" never varies, an upward line is not an illustration of a functional relationship.

In the matter of Horizontal lines, for any x-value, you get the equivalent y-value. These are described as Constant functions.
