Zeros are the solution to functions. When written in relation to x, or the equations they were derived from (example (x-1)), they become factors. These factors all together multiply out to create the original function. Division is important in this process because it gives the phrases that were multiplied out to make the function- in other words, the factors. The degree of the polynomial represents how many zeros it will have. This does not in fact say how many factors a function will have, mainly because of repeating factors.

Even and Odd Functions ActivityEven and odd functions share key similarities and big differences. They are both symmetric in different ways, even functions having y-axis symmetry and odd functions having origin symmetry.
Checking to see if a function is even or odd is a simple process. Plug (-x) into the equation. If you get the exact same thing you started with, the function is even. If you get the exact opposite of the function you started with, the function is odd. Functions that are neither even nor odd I'm assuming don't have either of the described symmetries. If I had a question it would be on that. My graphs were similar in shape to the actual graphs. The only differentiating factor was the size, which only occurred because I did not expect the skateboard to travel so far. The 21 inch ramp definitely had the highest maximum, which means it sent the skateboard the furthest. This was followed, predictably in order, by the 14 inch and 7 inch ramps.
The zeros of these graphs stand for when the skateboard was not moving. The skateboard could take longer or shorter to reach zero again based on the momentum each ramp gave it. The slope of the graph represents the rate at which the skateboard is traveling. Obviously, the steepest points of the parabolas were at the beginning, when the skateboard had the most momentum off of the ramp. The slopes fell fastest right after the maximum, and this was because gravity was pulling it down the second ramp: the driveway. |
