## What is the truth about relations and functions?

A function is a relationship between quantities that has one output for each input. A relation is one that has more than one output for an input. The vertical line test can show that a graph of a relation is a function.

## Which statement is are true about functions?

All functions have an independent variable. The domain of a function is its range. An example of a functional relation is a vertical line. A horizontal line is an example functional relationship.

**What is true for all functions? **

All functions have an independent variable. The domain of a function is its range. An example of a functional relation is a vertical line. A functional relationship can also be described as a horizontal line. A function’s output value can only correspond to one input value.

### Which of the statements are true of functions check all that apply?

### How is function represented?

Functions are typically represented by a function rule, where the dependent variable, or y, is expressed in terms of the independent variable, (x). An ordered pair is a pair of input and output values. It can be described as (a,b). These ordered pairs can be plotted to a graph.

**How do I know if a graph represents a function? **

Use the vertical line test in order to determine if a graph is a function. If a vertical line crosses the graph at a single point and touches it at other points, the graph is a function. If the vertical line touches more than one point of the graph, the graph is not considered a function.

## What is the difference of function and relation?

Relation – In maths, a relation is a collection of ordered pairs that contains an object from one set and another set. Functions are the relation between the set and the outputs. Functions are the only way to say that each input in the set (X) has one output in the given set (Y).

## What are the four types of functions?

The various functions are as follows

- Many to one function.
- One to one function.
- Onto function.
- One and onto function.
- Constant function.
- Identity function.
- Quadratic function.
- Polynomial function.
