ANSWER and EXPLANATION
f) The y-intercept of a graph is the point where the graph touches/intersects the y-axis of the coordinate grid.
Therefore, the y-intercept for the given graph is:
[tex](0,-3)[/tex]
g) The domain of a function is the set of all input values for which the function is valid. In other words, it is the set of all x-values of the function.
From the given graph, we have that the domain of the function is:
[tex](-\infty,\infty)[/tex]
h) The range of a function is the set of all output values for which the function is valid. In other words, it is the set of all y-values of the function.
From the given graph, we have that the range of the function is:
[tex]-3\cup[0,\infty)[/tex]
That is the answer.
