Domain and Range from Graphs

Learn to find domain and range from graphs and tables!

Domain and Range Below you will find the video to assist you in completing the assignment. Fill in the blank with the answer that correctly completes the sentence. A graph with points that are not connected is called a discrete graph. A graph that has a line that is connected is called continuous graph. Discrete vs. Continuous Click on each graph and determine if the graph is continuous or discrete. Discrete Continuous Solid vs. Dashed Click on the correct circles and lines that correspond to each Inequality Sign. Inequality Sign Circle Line < less than _ _ _ _ _ _ _ _ _ > greater than ---------------- > greater than or equal to _ > less than or equal to _ Domain is the set of all: x-values y-values x-intercept y-intercept We measure Domain from Left to right bottom to top Range is the set of all: x-values y-values x-intercept y-intercept We measure Range from Left to right bottom to top Mix Practice Fill in the blanks that correspond to each graph or table.
