Question 1143817: The equation y = -x^2 + 10 models the flight of a projectile where y is the height of the projectile in meters x seconds after launch. Determine the height after:
A) 1 second
B) 3 seconds
C) 10 seconds

I know that this is probably an extremely easy problem, but I don't know where to start. I figured that you were supposed to replace a, b, and c with the x in the problem, but there are two, and I thought that would mess it up. This is for my summer packet, so there's no real rush, I just can't seem to find any online examples of this type of question. Thank you in advance!
