The height y of a ball (in feet) is given by the function y = – 15 x + 2x + 4
and x is the horizontal distance traveled by the ball. how high is the ball when it
leaves the child's hand?

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
