Domain And Range Of A Function Activity
Only use graphs a l for this page.
Domain and range of a function activity. Teaching domain and range. Match each domain and range given in this table with a graph labeled from. Examples of domains and ranges from graphs important notes about domains and ranges from graphs.
On the attached page. Given a function in function notation form identify the domain and range using set notation interval notation or a verbal description as appropriate. Range describes all the dependent values in a function.
To find the domain of a function just plug the x values into the quadratic formula to get the y output. An example is the limit of x 1 as x goes to 1 is equal to zero because when looking at the graph when the domain x is equal to 1 the range y is equal to zero. For instance one way the domain and range is used in calculus is when evaluating limits.
This compilation of domain and range worksheet pdfs provides 8th grade and high school students with ample practice in determining the domain or the set of possible input values x and range the resultant or output values y using a variety of exercises with ordered pairs presented on graphs and in table format. Discrete functions are derived from sets of data which have gaps in them. Finding the domain and range of a function is used and expanded on in a variety of ways after precalculus.
The domain of a function is the collection of independent variables of x and the range is the collection of dependent variables of y. As such they are described by sets of ordered pairs x y the domain and range of these functions are described in brackets with each individual value listed. Read the attached page of notes first below beginning this activity.
Identifying the domain and range of a function just by looking at its formula can be difficult. To find the range of a function first find the x value and y value of the vertex using the formula x b 2a. As you teach your students about functions and how they work you will have to include a unit on domain and range.
