Equations and functions are not the same thing, but they can be related in several ways. In this video, we obtain a function from an equation. The function represents the same relationship between the …

Many functions are equations. But, they don't have to be. If you have a set of ordered pairs where each x-value relates to only one y-value, then you have a function. For example: { (2,5); (3,8); (5,7); (-3,6) …

A function is defined by the rule that for every input value (independent variable), there is a unique output value (dependent variable). The key criterion for a relationship to be a function is that each …

If any x-coordinate goes with two or more y-coordinates, then the relation is not a function. Graphically, if any vertical line passes through two or more points, then the graph (or relation) is not a function.

About this unit A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions. Unit guides are here! Power up your …

If an equation has exactly two variables involved in it, there is likely a relation between those variables, which is implied by the equality of both expressions. Rearranging to solve for the variable you want …

Think of linear as just a line. A linear function is one that, when graphed, forms a line. Linear functions are in the form: f(x) = ax + b, where a and b are constants.

How can you determine whether a function is even, odd, or neither by using just the equation of the function and not by graphing it?

If we get an expression that is equivalent to f (x), we have an even function; if we get an expression that is equivalent to -f (x), we have an odd function; and if neither happens, it is neither!
