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 …

A function-- and I'm going to speak about it in very abstract terms right now-- is something that will take an input, and it'll munch on that input, it'll look at that input, it will do something to that input.

Introduction to the domain and range of a function Learn Intervals and interval notation

What are rational functions? How do we plot them? What is their domain and range? Let's find out. We break down the definition of the function given in set-builder form and plot the graph by connecting …

Our function definition is now complete, but a function definition just defines how to perform a task. To actually perform that task, we still need to call the function.

The range of a function is the set of all possible outputs the function can produce. Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more limited set of …

The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0.

Understand how the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, chloroplasts, and ribosomes contribute to cellular function and organization. Discover how …

When you write f(x), it tells us that there's a function called f whose output value comes from input called x. Functions are evaluated at certain input values by replacing it with a number; for example, f(2) …

Once functions have been introduced, you should always assume f (x) is referring to a function named "f" with input value of "x". If it was multiplication, it would be written as "fx".
