write an equation for a function at has a graph with the given characteristics. the shape of y=|x| is reflected across the y-axi

Luba_88 [7]

Refrection across the y-axis changes the function to y = |-x|.
Vertical stretch by a factor of 1.5 changes the graph to y = 1.5|-x|
Shifting the graph by 4 units downward changes the graph to y = 1.5|-x| - 4

Required equation is y = 1.5|-x| - 4
