Answer 1

the parabola equation is of the form

\(ax^2+bx+c\)

is a>0, then parabola opens upwards
if a<0, then parabola opens downwards

Answer 2

compare
at^2+bt+c
with
-16t^2 +250t

Answer 3

So, it would open downwards because 250 is bigger than 16?

Answer 4

Oh wait, actually it would open upwards because 16^2 is bigger than 250.

Answer 5

we don't check whether anything is bigger or not.

we check the 'a' value

Answer 6

Ohh, SO it would be downwards because the value of 250 is larger than the value of 16?
