Domain And Range From A Graph
The range is the set of possible output values which are shown on the y axis.
Domain and range from a graph. Keep in mind that if the graph continues beyond the portion of the graph we can see the domain and range may be greater than the visible values. Vertex is at 1 4 and it opens upward. Then since the vertex is the low point take the primary square root of 4 to get 2 so range is y 2.
Another way to identify the domain and range of functions is by using graphs. The range is all the values of the graph from down to up. The range is the set of possible output values which are shown on the latex y latex axis.
Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the x axis. Substitute 1 into the quadratic to get 1 2 2 1 5 1 2 5 4. Keep in mind that if the graph continues beyond the portion of the graph we can see the domain and range may be greater than the visible values.
