I'm stuck on this one.
9) Find the [...] range of f if -2 < x < 3 and f(x) = x^2 - 2x.
This is what I've tried:
I'm sorry, but I don't know how to go about this at all, so I have no work to show for number 10

I don't know how to continue. Also, number 10 stumped me too.-2 < x < 3
-2x < x^2 < 3x
-2x - 2x < x^2 - 2x < 3x - 2x
0 < x^2 - 2x < x
10) The function h(t) = -4.9t^2 - 24.5t models the height, h, of a golf ball above the ground in meters, t seconds after the ball is hit. Find the domain of this function.
