**SOLUTION Determine whether each relation is a function**

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. A function assigns exactly one output to each input of a …... A function is a relation where for every x there is exactly one value for y. To classify relations as functions when you are given a list, a mapping diagram, or a table, check the x-values. If there are two x-values that are the same but have different y-values, then the relation is not a function.

**How to determine if a relation is a function Quora**

24/01/2012 · To be more specific, this is the "vertical line test". You sweep a vertical line across the function (often done with a pencil edge). As long as the line / edge touches only one point (or none) of the graph for any X value, the graph is a function.... You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function! Watch this tutorial to see how you can determine if a relation is a function.

**How can you tell if a relation is a function?**

The relationship between the cosine and sine graphs is that the cosine is the same as the sine — only it’s shifted to the left by 90 degrees, or π/2. The trigonometry equation that represents this relationship is Look at the graphs of the sine and cosine functions on the same coordinate axes... One can determine if a relation is a function by graphing the relation, drawing a vertical line on the graph and then checking whether the line crosses the graph at more than one point.

**Functions- How to tell if a relation is a function**

Trigonometric functions are periodic so they are many-to-one. It is therefore important to define the domains and ranges of their inverses in such a way the the inverse funct … ion is not one-to-many.... This algebra lesson explains how to use the vertical line test to see if something is a function or not . If we've got the picture of a critter (i.e. the graph), there's an easy way to tell if it's a function or not. It's called THE VERTICAL LINE TEST: If you can draw a vertical line anywhere on a graph so that it hits the graph in more than one spot, then the graph is NOT a function

## How To Know If A Relation Is A Function

### In mathematics, an expression is called well-defined or unambiguous if its definition assigns it a unique interpretation or value. Otherwise, the expression is said to be not well-defined or ambiguous. A function is well-defined if it gives the same result when the representation of the input is changed without changing the value of the input.

- When each input in a relation has exactly one output, the relation is said to be a function. To determine if a relation is a function, we make sure that no input has more than one output. For a
- The phrase “a function of” is used to tell the user what the independent variable is. For For instance, the phrase “ y as a function of x ” indicates that the independent variable is x
