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! …

If you're talking about evaluating functions, then it works the exact same way as evaluating algebraic expressions. Replace all instances of the variable with its substituted value, and …

This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing …

Some equations are hard to solve exactly with algebraic tools. We can always solve an equation by graphing it, although the solution might not be exact. This is an example of how to solve a …

This video is about composing functions, which is the process of building up a function by composing it from other functions. It explains how to evaluate the composition of functions …

To find the inverse of a function, you must not only invert the operations but also the steps in which you build the original function. To start, let's list the steps to build the original g (x) function:

The first step is to find the answer of the function within the function. The second step is to input the answer of the function of the function in to the function on the outside.

This topic covers: - Adding, subtracting, and multiplying polynomial expressions - Factoring polynomial expressions as the product of linear factors - Dividing polynomial expressions - …

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 …

Where ever input thresholds (or boundaries) require significant changes in output modeling, you will find piece-wise functions. In your day to day life, a piece wise function might be found at …
