write an equation for a function at has a graph with the given characteristics. the shape of y=|x| is reflected across the y-axis. this graph is then vertically stretched by a factor of 1.5. finally, the graph is shifted 4 units downward.
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
