I want to create a quadratic equation. I understand the form is Ax^2 + Bx + C = 0. However, the instructor says we can use the form y = +/- x^2.
If I wanted to create a quadratic equation simulating a bird falling out of the sky to the earth...where would I begin? I'm not sure what factors to bring into such a question? The initial height? The speed of flight? How do I translate any question regarding a bird falling to hit the earth in this quadratic equation? This is the first time I've studied this stuff at all, so I could use a little direction in construction a word problem.
