ProjectileMotion Aprojectileisshotupintheairfromthegroundwithaninitial velocity of 84 feet per second. Using y = -16t2 + 84t, write an equation to model the situation and use the discriminant to determine if the projectile will reach a height
of 200 feet.

If a quadratic function has been vertically compressed, does that mean the
parabola is wider or narrower than the parent quadratic function f(x) = x2?
For all real values of the domain, describe the relationship between the graphs of
