The domain and the range of a graph are the set of input and output values on the graph; The domain of the graph is (-2,5]. The range of the graph is (-5,2).
The domain of a function is defined as the set of all the possible input values that are valid for the given function.
The range of a function is defined as the set of all the possible output values that are valid for the given function.
To find the domain by looking at a graph, we need to see the smallest x-value and the largest x-value.
This means that the point itself does not belong to the domain, so here we need to use an open interval symbol, which is (,
For a given function f(x), we define the domain as the set of the possible inputs for that function.
On the graph, the x values starts at x = -2, and it ends at x = 5
This means that, the domain of the graph is (-2,5]
On the graph, the y values starts at y = -5, and it ends at y = 4 (with an open circle)
This means that, the range of the graph is (-5,2)
