Actually, on a Cartesian plane, we only use the domain and range of real numbers (not rational numbers), so we do not include imaginary numbers. These are not on our normal Cartesian (x …

Algebra 1 Lesson 5: Introduction to the domain and range of a function Intervals and interval notation

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.

Algebra 1 Lesson 5: Introduction to the domain and range of a function Intervals and interval notation

This topic covers: - Evaluating functions - Domain & range of functions - Graphical features of functions - Average rate of change of functions - Function combination and composition - …

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 …

Let's take a look at an example where plotting a graph can help us figure out the domain and range of a function. Even if that function is not a polynomial. We break down the definition of …

Determine the domain of a function according to the algebraic limitations of that function.

Compare and contrast domain and range given graphs of partial quadratic and exponential functions, where the ends of the shown graph vary among points, and arrows.

Given a graph of a partial linear, quadratic, or exponential function, select the inequality that represents its domain or range. Given a domain or range in inequality form, select a graph of a …
