A model rocket is launched from a platform. Its trajectory can be
approximated by the function
h(d) = -0.01d2 + 2d + 1, where h is
the height, in metres, of the rocket and
d is the horizontal distance, in metres,
the rocket travels. How far does the
find d
rocket land from its launch position?
Express your answer to the nearest
tenth of a metre.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
