Algebra 2 Domain And Range Set Notation

Oo oo where oo stands for infinity.

Algebra 2 domain and range set notation. Fn n 2 1 if its domain is the set 1 3 5. The range defines the possible values for y. Write the domain and range in set builder notation and interval notation. 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 for example latex left x 10 le x 30 right latex describes the behavior of latex x latex in set builder notation.

The function must work for all values we give it so it is up to us to make sure we get the domain correct. Therefore this statement can be read as the range is the set of all y such that y is greater than or equal to zero. 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. The domain defines the possible values for x.

State the range of the function. Show the domain and range in the mapping diagram below. The range of f x x 2 in set notation is. Eq y 6x 2x 2 eq quadratic function.

What is the domain and range in set notationa and interval notation of. If we are given an equation or graph we might use inequalities or intervals to describe domain and range. In its simplest form the domain is the set of all the values that go into a function. The domain of a non composite quadratic function is usually the set of all.

Y y 0 r indicates range. 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. A determine the minimum and maximum values x. Set builder notation is very useful for defining domains.

In this section we will introduce the standard notation used to define sets and give you a chance to practice writing sets in three ways inequality notation set builder notation and interval notation. We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers. When using set notation inequality symbols such as are used to describe the domain and range. Answer the following questions based on this graph.
