Chapter 10-Relations and Functions, Practice Test

What kind of functions have holes in their graphs? Here, the teacher guides the class on how to use the simplified function of a rational function to aid in the graphing of the original rational function. T-tables are used in order...

Turn your class upside down as they explore the reciprocal functions. Scholars use the unit circle to develop the definition of the secant and cosecant functions. They analyze the domain, range, and end behavior of each function.

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...

After defining a simple function from a word problem, a short video shows how to find its domain and range. The instruction reinforces the definitions of domain and range with a concrete example.

We look at several examples of functions and see their domain. Sal writes the domain in set notion and shows how different functions can have different input values that cause the function to be undefined.

Starting from a brief look at functions and the mapping of domains to ranges, Sal starts with an intuitive sense of what a function inverse is. Using an example, he then shows how to find the inverse of a function and how the graph of...

Take your kids on a tour of graphing rational functions. Using this TI instructional activity, high schoolers identify the end behavior of their functions. They find the domain and range, describe end behavior, and look at asymptotes and...

Break it up into pieces to solve the problem. Individuals watch a video on how to graph and determine the equation and values of piecewise functions. Viewers then work several exercises to practice evaluating a piecewise function at...

What is a function? What is a one-to-one function? Using examples of domain and range and looking at different mappings, this video looks at the definition of a function and more specifically, the definition of a one-to-one function.

With so many types of graphs, don't let your learners get stuck figuring out which one to use. To track how Zoe spent her allowance, use this interactive lesson to review all the types of graphs and pick the best one to display the data....
