12. A skier's jump can be modelled by the function y = -4.9x² + 3.2x + 2.5, where y is the skier's height above the
exis
ground, in metres, and x is the time, in seconds, that the skier is in the air.
a) Use technology to graph the function, then draw a sketch if the graph.
b) Determine the coordinates of the vertex.
c) Determine the skier's maximum height and state the range of this function.
