40 Write The Domain And Range Of G Using Interval Notation New

Swbat write the domain and range of a graph using interval notation by comparing it to set builder notation.

Write the domain and range of g using interval notation. For the following exercises write the domain and range of each function using interval notation. In interval notation the domain is 1973 2008 and the range is about 180 2010. In the previous examples we used inequalities and lists to describe the domain of functions.

In interval notation there are five basic symbols to be familiar with. 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. Y 3x 1 y x 2 3x 2 and y x 3.

Stick with those and you will have a polynomial. In interval notation we write. 3 x domain range 4 00 10 8 7 4 3 2 1 av 5 4 3 2 1 3 4 3 4.

Do you notice that each one of those functions has powers of x that are whole numbers. 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. The graph may continue to the left and right beyond what is viewed but based on the portion of the graph that is visible we can determine the domain as latex 1973 le t le 2008 latex and the range as approximately latex 180 le b le 2010 latex.

For f x x 2 the domain in interval notation is. Interval notation is a method used to write the domain and range of a function. Let me give you some examples of polynomial functions.
