Without changing any x coordinates,all of the y coordinates are transformed to their opposite numbers (or additive inverses) and then are rescaled by a factor of 4.In terms of graph,the graph of y= -4f(x) is given by flipping the graph of y=f(x) vertically (i.e.upside-down) and then stretching the graph of y=f(x) vertically by a factor of 4.
