Please help i’m confused

This is the graph of a parabolic function.

Without seeing the dropdown menu, I assume that is what the question is asking. It's parabolic: the shape is like an upside-down u or an upside-down v.

Michael Jordan's hang time is .9 seconds.

The parabola starts at 0 seconds, and ends at t = .9 seconds.

The maximum height is about 1 meter.

The vertex or very top of the parabola is at h = 1.

For t between t = .5 and t = 1, the height is decreasing/falling/going down.

I can't tell this one for sure unless I can see the dropdowns. But I can say that from .5 to 1, whatever it is, it's dropping or falling, because the height is getting less and less.
