Function h(x) = -0,001x^2 + x. A cannonball covers a trajectory that you can trace with h(x) = -0,001x^2 + x.

h is the height of the cannonball from the ground in metres and x is the covered distance horizontally

1a. Fill in the table

1b. What would be the highest altitude the cannonball reached?

Thanks!

h(x)= y   for the table....just substitute the value of 'x' in to the equation to find the 'y' value for the table

Example   x = 0

h(x) = y = -0.001(0)^2 + 0 =    0

h(x) = y = -0.001(200)^2 + 200 = 160

Fill in the rest of the table the same way and you will find the highest value (given the values of x that you have in the table)
