a tennis player heyton lewitt, is able to out think his opponents by hitting a shot and making the opposition think that it will go out but instead it lands perfectly on the base line (15m from net). his opponent saw through this plan and was able to mentally calculate that the path followed the ball corresponded to the mathematical equation of...

y= -x2 + 29.9x + 3

(y= negative x squared plus 29.9x plus three)

Q1.

Iva is 14.9m from the net and hits the ball straight back so that the tennis ball just missed the net which is 1metre high. is this a safe shot.. will it land it?

Q2.construct a better shot for Heyton that would still give him a similar advantage but not be as obvious that he may have been a drug cheat.

PLEASE HELP ME!
