Some Examples of Functions. x 2 (squaring) is a function; x 3 +1 is also a function; Sine, Cosine and Tangent are functions used in trigonometry; and there are lots more! But we are not going …

A function is a rule that relates how one quantity depends on other quantities. Example 1 A particular electrical circuit has a power source and an 8 ohms (Ω) resistor.

For example, we can use sets of ordered pairs, graphs, and mapping diagrams to describe the function. In the sections that follow, we will explore other ways of describing a function, for …

In Algebra 1, we will study linear functions (much like linear equations) and quadratic functions. As you progress into Algebra 2, you will be studying exponential functions. I have several lessons …

A function is a rule which maps a number to another unique number. In other words, if we start off with an input, and we apply the function, we get an output. For example, we might have a …
