how can you tell if a relationship is a function?

if you have a set of x and y values. it would be a function if every x value is paired with exactly one y value every x value can only have one y. value. let's take a look at a couple examples and some ways to represent relations.

It is important to remember that a function does not have to be even or odd. Most functions are neither even nor odd. To determine whether the function \begin{align*}y=3(x+2)^2+4\end{align*} is even or odd, apply the test for both types.

How can this be true? A relation is any set of ordered pairs. A function is a set of ordered pairs where there is only one value of \begin{align*}y\end{align*} for every value of \begin{align*}x\end{align*}.

If you think of the relationship between two quantities, you can think of this relationship in terms of an input/output machine. If there is only one output for every input, you have a function. If not, you have a relation. Relations have more than one output for at least one input.

A function for which every element of the range of the function corresponds to exactly one element of the domain. One-to-one is often written 1-1. Note: y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test.

y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.

No, every straight line is not a graph of a function. Nearly all linear equations are functions because they pass the vertical line test. The exceptions are relations that fail the vertical line test.

if you can draw any vertical line that intersects more than one point on the relationship, then it is not a function. This is based on the fact that a vertical line is a constant value of x, so if there is one input, x, with more than two outputs, y, then it breaks the function rule.

ANSWER: Sample answer: You can determine whether each element of the domain is paired with exactly one element of the range. For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

3 Ways to Determine if Proportional Relationships Exist: To determine if a simple given proportion is true, look at the fractions. If these ratios (fractions) both reduce to the same value, the proportion is true.

A special relationship where each input has a single output. It is often written as "f(x)" where x is the input value. Example: f(x) = x/2 ("f of x equals x divided by 2") It is a function because each input "x" has a single output "x/2": • f(2) = 1.

Answer: The ellipse is not the graph of a function. Step-by-step explanation: If you can draw a vertical line on the graph that intersects the graph in two or more points, the relation shown is not a function.

Mathwords: One-to-One Function. A function for which every element of the range of the function corresponds to exactly one element of the domain. ... Note: y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test.

A function is a relation between domain and range such that each value in the domain corresponds to only one value in the range. Relations that are not functions violate this definition. They feature at least one value in the domain that corresponds to two or more values in the range.

A function is a process by which a relationship between sets is defined - this relationship is such that for every input there is exactly one output. The domain of a function is the set of all acceptable inputs to that function.
