This domain is closed. To figure out whether the domain is bounded or unbounded, ask yourself if you could draw a circle on the graph of the domain that would contain all of it. If you can't, the domain is unbounded.

WebSolution : An open circle on the graph shows that the endpoint of the line is not included in the graph. A closed circle means that the endpoint is included. So, x cannot be -5, but it can be 11. Domain = {x ∊ R -5 < x ≤ 11} Range = {2, 6} The graph passes the vertical-line test. So, the graph is a function. Example 3 : Solution : burkholder\u0027s fabrics denver pa coupons

The range is the set of possible output values, which are shown on the y -axis.

WebThe reason is simple: on an open interval, the endpoints are OUTSIDE the domain and thus not part of the function's definition. Thus, they are not max, min nor any other part of the function. However, on a CLOSED interval, the endpoints of a differentiable function are ALWAYS local extrema. Web4.1.1 Recognize a function of two variables and identify its domain and range. ...
