Algebra 2 Domain And Range Set Notation
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.
Algebra 2 domain and range set notation. Write the domain and range in set builder notation and interval notation. Fn n 2 1 if its domain is the set 1 3 5. The range defines the possible values for y.
Y y 0 r indicates range. When using set notation inequality symbols such as are used to describe the domain and range. State the range of the function.
Show the domain and range in the mapping diagram below. Y gx is completely defined by the graph shown below. The domain defines the possible values for x.
If we are given an equation or graph we might use inequalities or intervals to describe domain and range. Set builder notation is very useful for defining domains. The range of f x x 2 in set notation is.
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. The function must work for all values we give it so it is up to us to make sure we get the domain correct. Eq y 6x 2x 2 eq quadratic function.
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. Since this is a vertical parabola that opens downward the y value of the vertex defines the max value. What is the domain and range in set notationa and interval notation of.
