How Do You Find the Domain and Range of a Relation?

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson. Using the coding formula listed, children learn to fluently estimate and calculate...

Domain to a math teacher makes perfect sense, but it can seem like gibberish to high schoolers. As it is laid out in clear terms, domain is introduced and explained among all types of functions throughout the handout. The first three...

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.

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.

Spread the data out on the range. The short video provides a definition of the range. Using a data set of five numbers, the resource calculates the range.

Mean, mode, median? What's the difference? How do you find them? The teacher focuses on explaining median in this video. She gives a good explanation and shows how to order a data set to find the median number. This given data set has an...

A straightforward explanation of domain and range. The domain of a set of coordinates are the X-values, and then range are the Y-values of the set.

Looking for the range of a set of numbers? Well, that means you are looking for the difference between the largest value and the smallest value. So first, write the numbers in order from least to greatest. Then identify the largest value...

The middle of the data is important, but what about the rest of it? The lesson shows learners the importance of the range, quartiles, and extreme values. Pupils practice finding each of these values from given data sets.
