course Phy 201
4:45 pm EST 6/9/14On the homework/assignments website, it said 1.16 under Other for assignment 01, but I only found 1.15. Is this what you're referring to? It is about graphing.
In the equation y = ax^2 + bx + c, here are my observations:
* The larger absolute value of a the more narrow, the smaller the wider it is. Negative numbers flip the parabola.
* For b, there's a small range that keep it just along the middle of x axis but most numbers make the parabola go the the left or right lower quadrants.
* The c moves it up and down the y axis.

Good.
