Exploring Domain and Range (Continuous)

Domain and Range Notes The x-axis on a graph goes left to right (horizontal).The y-axis on a graph goes up and down (vertical). Domain and Range Video Watch the video below to see two examples of how to determine the domain and range of a function from a graph. Then answer the question below. Click on the empty blanks to complete the sentences with the correct terms. If a graph has arrows, that means the graph does not end. It goes on forever.If a graph has a closed circle for an endpoint, that means the point is included in the domain and range and the inequality includes an equal sign such as ≥ or ≤.If a graph has an open circle for an endpoint, that means the point is NOT included in the domain and range and the inequality should be > or <. Domain and Range Relation 1 Use the graph below to help you answer the questions that follow. The xleftboundand xrightboundsliders will adjust the green shaded area to help you determine the domain. The ylowerboundand yupperboundsliders will adjust the purple shaded area to help you determine the range. What is the domain of Relation 1? -3 ≤ x ≤ 2 -3 ≤ y≤ 2 -2 ≤ x ≤ 8 -2 ≤ y ≤ 8 What is the range of Relation 1? -3 ≤ x ≤ 2 -3 ≤ y≤ 2 -2 ≤ x ≤ 8 -2 ≤ y ≤ 8 Domain and Range Relation 2 Use the graph below to help you answer the questions that follow. The xleftboundand xrightboundsliders will adjust the green shaded area to help you determine the domain. The ylowerboundand yupperboundsliders will adjust the purple shaded area to help you determine the range. What is the domain of Relation 2? 0 < x< 4 0 < y< 4 -2 < x< 1 -2 < y< 1 What is the range of Relation 2? 0 ≤ x < 4 0 ≤y< 4 -2 < x< 1 -2 < y< 1 Domain and Range Relation 3 Use the graph below to help you answer the questions that follow. The xleftboundand xrightboundsliders will adjust the green shaded area to help you determine the domain. The ylowerboundand yupperboundsliders will adjust the purple shaded area to help you determine the range. What is the domain of Relation 3? -6 ≤ y < 4 -6 < y ≤ 4 -6 ≤ x < 4 -6 < x ≤ 4 What is the range of Relation 3? 0 ≤ y < 5 0 < y ≤ 5 0 ≤ x < 5 0 < x≤ 5
