Use notations to specify domain and range In the previous examples, we used inequalities and lists to describe the domain of functions. We can also use inequalities, or other statements that might define sets of values or data, to describe the behavior of the variable in set-builder notation.

Some students I notice are writing the intervals for domain and range in interval notation instead of set builder notation. I purposely planned for the students to use set builder notation first to develop a deeper understanding of inequalities before working with interval notation.

We can write the domain and range in interval notation, which uses values within brackets to describe a set of numbers. In interval notation, we use a square bracket ( when the set includes the endpoint and a parenthesis ( to indicate that the endpoint is either not included or the interval is unbounded.Write sets using set-builder, inequality, and interval notation. Describe sets on the real number line using set builder, interval, and inequality notation. There are several ways to define sets of numbers or mathematical objects. The reason we are introducing this here is because we often need to define the sets of numbers that make up the inputs and outputs of a function.In mathematics, the domain of a function, f (x), is the set of all values of x that can be plugged into f (x) to produce a defined function. The range of a function, f (x), is the set of all.

SWBAT write the domain and range of a graph using interval notation by comparing it to set builder notation. Big Idea To have a deeper understanding of interval notation from inequalities and how the square bracket includes the number and the parentheses does not include it.

Read MoreSet-builder notation can be used to describe sets that are defined by a predicate, rather than explicitly enumerated. In this form, set-builder notation has three parts: a variable, a colon or vertical bar separator, and a logical predicate. Thus there is a variable on the left of the separator, and a rule on the right of it.

Read MoreInterval notation is a method used to write the domain and range of a function. In interval notation, there are five basic symbols to be familiar with: open parentheses (), closed parentheses (), infinity (imagine an 8 sideways), negative infinity (an 8 sideways with a negative sign in front of it) and union (a symbol similar to an elongated U).

Read MoreSet-builder notation is one way we have of representing a set, and it is a good notation to use if the set has infinitely many objects in it. We use set-builder notation to represent a set, S, as.

Read MoreIn set-builder notation, we could also write the set of all real numbers that are not zero. For the reciprocal squared function we cannot divide by so we must exclude from the domain. There is also no that can give an output of 0, so 0 is excluded from the range as well.
