Something not right here.
According to your equation, it is not launched from ground level, but from a height of 4 units.
Furthermore it is launched with a downwards velocity of 1 unit of distance/ 1 unit of time
domain: t ≥ 0
check for a typo
a projectile is laucnhed from the ground level and its height can be modeled as a function of time by the equation h=4-t-50t^2
What are the reasonable domain and range of this problem

40t-5t^2
