One unit to the left: y = x + 1
One unit to the right: y = x - 1
We can find that the formula is:

We are told that the cannonball reaches its maximum height at t = 4.5 seconds. To find the maximum height, let's just plug this into the formula:

The height is 324 feet. We're done!
Length of DE = 3-(-1) = 4
SIDE DE is a vertical line
horizontal distance between E and F is 3 - (-2) = 5
So the area of triangle DEF = 0.5 * 4 * 5 = 10 sq units
