A. All of my prediction graphs were similarly shaped to the actual values graphs. The 21 inch ramp's actual values graph had a gentler slope while rising and falling than my predication graph had. The maximum distance that the skateboard reached was almost the same for both graphs. The 14 inch ramp's actual values graph closely matches except for the rising slope which was gentler than my prediction. My prediction for the 7 inch ramp was the farthest away from being accurate if you compared the three graphs. In my prediction the slope is steeper at the rise and then gentler than the actual values graph towards the last half of the graph.
B. The zeros on my graph represents the original starting point.
C. All of the graphs have the same zero, which is the point (0,0). This is the starting point where the skateboard hasn't moved and time hasn't passed yet. As you lower the ramps the maximum feet traveled decreases. An example, being that the 21 inch ramp had a maximum of 62 feet, and the 7 inch ramp had a maximum of 42 feet. The skateboard from the 21 inch and 14 inch ramps reached a maximum and then began traveling back towards the starting point while the skateboard from the 7 inch ramp stopped moving after it reached its maximum.
D. When the graphs are rising the fastest is when the skateboard is being let down the ramps. This means that the ramps help speed up the skateboards. The graph decreases the fastest when the initial speed from the ramps wears off and the skateboard starts moving down the pavement towards the starting point. This means that the skateboard is gradually traveling slower and slower.
