5. To figure this out you must find when y = 0

-16t^2 = -200

t^2 = 12.5

Square root

t = 3.54 C

6.

Axis of symetry = -.5 (always a vertical line down vertex)

Vertex = (-.5, -6.5) (the minimum of the graph)

B

7. To find maximum height you must find the vertex

The maximum height is 549 feet after 5.75 seconds

C

9. Solve for X

x^2 = 1

Square root

X = plus or minus 1

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
