This is an absolute value function.

Were it not for that "-3" in f (x) = 3/4 |x|-3, the vertex of the graph would be on the x-axis.

But that "-3" causes a downward vertical translation of 3 units.

Thus, the smallest possible y value is - 3; there is no limit on y otherwise.

Range is [-3, infinity]
