An object is thrown in the air. The trajectory of the object us represented by the equation Y=-1/5x²+2x+4. Y is the height of the ball in feet at the horizontal distance of x feet from the thrower.
Complete a table wich models the trahectory of the ball.
--------------------
----
Pick values for x and find y. Positive x only, negative makes no sense.
----
x = 0, y = 4
x = 0.5, y = 4.95
x = 1, y = 5.8
x = 2, y = 7.2
etc
----
Use Excel if you have it.
Here's a table from graph software.
