This can be seen by projecting thegraph onto the -axis, as shown in red in Figure 2.y, −3ygy-1-2-3-4-512345 The entire graph of the function is shown in the figure below.Write the domain and range of using interval notation.Sample Questiongg It is possible to determine the domain and range of a function from its graph. The domain is the set of all the numbers that appear as -coordinates of points on the graph. The range is the set of all the numbers that appear as -coordinates of points on the graph. (a) Domain of the function The numbers that appear as -coordinates of points on the graph make up the interval . This can be seen by projecting the graph onto the -axis, as shown in red in Figure 1.
