An egg is thrown of the top of a building. Its height in meters above the ground can be approximated by the polynomial 300 + 2t - 4.9t2 (the second t has a exponent of 2) where t is the time since it was thrown in seconds?
online, use ^ for exponents, as in t^2
Now, was there a question in there somewhere? (Aside from the fact that you appear to be asking us about this egg, rather than telling us.)
The function can be used to answer it, I'm sure.
