For a relation to be a function, use the Vertical Line Test: Draw a vertical line anywhere on the graph, and if it never hits the graph more than once, it is a function. If your vertical line hits twice or more, it’s not a function.

This relationship is commonly symbolized as y = f(x)—which is said “f of x”—and y and x are related such that for every x, there is a unique value of y. That is, f(x) can not have more than one value for the same x. To use the language of set theory, a function relates an element x to an element f(x) in another set.

In the slope formula, the numerator is 0, so the slope is 0. If we use m = 0 in the equation f(x)=mx+b f ( x ) = m x + b , the equation simplifies to f(x)=b f ( x ) = b . In other words, the value of the function is a constant. This graph represents the function f(x)=2 f ( x ) = 2 .

An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (x-value) by 3 to find each output number (y-value).

Straight Line Graph A general linear function has the form y = mx + c, where m and c are constants. The fundamental rule at the rear of sketching a linear graph is that we require only two points to graph a straight line.

An algebraic rule is a mathematical expression that relates two variables and is written in the form of an equation. There are many constant algebraic rules, such as area = length x width. You can also create your own rule when given a set of variables.
A function table has values of input and output and a function rule. In the function rule, if we plug in different values for the input, we get corresponding values of output. There is always a pattern in the way input values x and the output values y are related which is given by the function rule.
The graph of the function is the set of all points (x,y) in the plane that satisfies the equation y=f(x) y = f ( x ) . If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.
