Answer:
Step-by-step explanation:
We can do this the easy way and just set up an inequality and let the factoring do the work for us. The inequality will look like this:

and when you factor this you get that
3 < t < 4
Between 3 and 4 seconds is where the projectile reaches a height higher than 192 feet. With a little more work and some calculus you can find the max height to be 196 feet.
Alright
This equation models a circle with a center of (-2 , 3) and a radius of 9
To check the point (6,3) how far is it from the center (-2,3):
using the distance formula:
therefore, this point lies INSIDE the circle, not on it nor outside it.
It is an interior point.
