Exercise Set 2.7: Functions and Graphs

Can you solve an equation graphically? Absolutely! This Algebra II lesson makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process of...

The key is ... After a day of instruction on key features of graphs, groups create a poster and presentation on the key features of their given function graph. The resource provides an extension activity of "telephone" using...

Relations, and functions, and line tests, oh my! An instructional slideshow demonstrates the definitions of a relation, a function, and the domain and range of a relation. Viewers then learn how to use mappings and vertical...

Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.

The short example shown in this video starts with a given set of numbers in the domain and the range that represents a function. One needs to map the points on a coordinate plane.

This short video looks at different points on a coordinate plane and answers a question about whether these points could represent a function. The answer is determined by looking at each point individually to determine whether, given a...

Sometimes a graph makes situations much easier to see. After learning about discrete and continuous graphs by watching a short video, scholars match graphs to real-world situations. The provided graphs are a discrete linear graph, a...

Offers a step-by-step explanation of a one-to-one function problem on inverse functions with restricted domains, clearly using the horizontal line test. Includes sample problems.

Create a graphical description. Pupils watch a video presentation starting with vocabulary on properties of a graph of a function and then use the vocabulary to find key features of graphs of a function. Scholars use three graphs in the...

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.
