SOLUTION
(f) The y-intercepts
This is where the graph cuts the y-axis. Looking at the graph, the graph cuts the y-axis at -3.
So the answer as an ordered pair is (0, -3)
(g) The domain of f
The domain is determined from the x-axis or the x-values. From the graph, the domain is defined for a set of all real numbers of x, from negative to positive infinity.
So in interval notaion, the domain is
[tex](-\infty,\infty)[/tex]
(h) The range is derived from the y-axis or y-values.
Looking at the graph, the range is defined for all set of y-values from -3, to 0 to positive infinity of real numbers.
So in interval notation, the answer is
[tex][-3]\cup[0,\infty)[/tex]
