#### Answer

Refer to the image below for the graph.

#### Work Step by Step

$f(x) =-4$ is equivalent to $y=-4$ RECALL: The graph of an equation of the form $y=k$ is a horizontal line whose y-intercept is $k$. The given equation has $k=-4$ therefore its graph is a horizontal line whose y-intercept is $-4$. The points on the line share the same y-value of $-4$. This means that the line contains the points $(-2, -4)$, $(0, -4)$, and $(2, -4)$. To graph $y=-4$, plot the three points then connect them using a line. (refer to the attached image in the answer part for the graph)
