The height , y meters, of an emergency flare fired upward from a small boat can by modelled by the function y= -5(x-4)squared+80, where x seconds is the time since flare was fired.
Describe how the graph of y= -5(x-4)squared+80 can be obtained by transforming the graph of y= x squared
Interpret the equation of the transformed function to find the maximum height reached by the flare and the time it takes to reach it, Graph the object, y=x squared and the image, y= -5(x- 4)squared+80
