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 …

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! …

We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world …

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 …

Test your understanding of Linear equations, functions, & graphs with these 22 questions.

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.

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 …

For each region or interval, the function may have a different equation or rule that describes it. We can evaluate piecewise functions (find the value of the function) by using their formulas or their …

Learn how to find the formula of the inverse function of a given function. For example, find the inverse of f (x)=3x+2.

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