EXAMPLES OF DOMAINS AND RANGES FROM GRAPHSImportant notes about Domains and Ranges from Graphs: Remember that domain refers to the x-values that are represented in a problem andrange refers to the y-values that are represented in a problem. Sometimes it isn’t possible to list all the values that x or y can be because the graphis continuous and made up of an infinite number of points, like a line, a ray, oreven a segment. In a continuous graph, to determine the domain, you should focus on looking leftto right of the graph. In a continuous graph, to determine the range, you should focus on lookingbottom to top of the graph. We use interval notation to help us describe the domain and range for graphs thatrepresent continuous situations. Please review the following information to help you describe the domain and rangefor three different types of continuous graphs.Example 1: A continuous graph with two endpoints.Domain: {-7 x 5} Notice that this graph has two endpoints, so the graph startsand stops and the domain covers all x-values between thetwo endpoints which makes it a continuous graph. Since the left and right endpoints are at (-7, -3) and (5, 1), thegraph covers all x-values between the x-values of -7 and -3. Notice that the first endpoint is a closed circle so it includesthat point; but the second endpoint is an open circle, so it doesnot include that point. Therefore, the graph covers all x-values -7 AND all xvalues 5 – we write that in interval notation as {-7 x 5}Important Note: To find the domain fora graph with twoendpoints, alwaysidentify the x-valuesof the point farthest tothe left and the pointfarthest to the right. For the range, youwant the y-values ofthe lowest point andthe highest point.Range: {-3 y 1} Notice that this graph has two endpoints, so the graph startsand stops and the range covers all y-values between the twoendpoints which makes it a continuous graph. Since the bottom and top endpoints are at (-7, -3) and (5, 1),the graph covers all y-values between the y-values of -3 and1. Notice that the first endpoint is a closed circle so it includesthat point; but the second endpoint is an open circle, so it doesnot include that point. Therefore, the graph covers all y-values -3 AND all yvalues 1 – we write that in interval notation as {-3 y 1}
Example 2 – a continuous graph with only one endpoint (so continues forever in theother direction)Domain: {x 0} (remember to focus on left to right of the graph fordomain of a continuous graph): Notice that this graph has one endpoint at (0, 0) and an arrow tothe right indicating that it continues forever in the positive xdirection. Therefore, this graph covers all x-values that are greater than orequal to 0 – there is no stopping point on the right side of thegraph. We write the domain in interval notation as {x 0}.Note: If the arrow werepointing to the left, thedomain would be thex-value. If the arrowwere pointing down, therange would the yvalue.Range: {y 0} (remember to focus on bottom to top of the graph forrange of a continuous graph): Notice that this graph has one endpoint at (0, 0) and an arrowpointing up indicating that it continues forever in the positive ydirection. Therefore, this graph covers all y-values that are greater than orequal to 0 – there is no stopping point on the upper side of thegraph. We write the range in interval notation as {y 0}.Example 3 – a continuous graph that has two arrows:Domain: {x all real numbers} (remember to focus on left toright of the graph to determine the domain for a continuous graph) Notice that this graph has an arrow on the left side of thegraph and an arrow on the right side of the graph. This indicates that the graph continues forever in the leftdirection and forever in the right direction. This means that the graph covers all possible x-values –we call that all real numbers in algebra. Therefore, we can write the domain in interval notation as:{x all real numbers}.Note: If one of the arrowswere pointing up and oneof the arrows werepointing down, then therange would be all realnumbers.Range: {y 0} (remember to focus on bottom to top of the graphto determine the range of a continuous graph) Notice that the graph’s lowest point is at (0, 0) (thebottom of the parabola) – indicating that the y-values startat 0. However, notice at the top of the graph there are arrowspointing up – this indicates the graph continues in thepositive y direction forever. So, the graph covers all y-values greater than or equal to0. We can write the range in interval notation as: {y 0}.

Entrepreneurial ecosystem models typically categorize the ecosystem elements into domains. The number and type of ecosystem domains vary from one model to another. There is a general consensus regarding the inclusion of some domains such as human capital, policy, and finance; other domains such as market access and quality of life are .
