(1) Attached figure 1 is the solution
By graphing the model of the data ⇒⇒⇒ red points
(-1,0), (1,-4), (2,-3), (4,5), (5,12)
and graphing the quadratic equations
∴ the solution will be choice (d)
d.] f(x) = (x-1)² - 4
======================================================

(2) Attached figure 2 is the solution
By graphing the model of the data ⇒⇒⇒ red points
(0,1), (1,4), (2,5), (3,4), (4,1)
and graphing the quadratic equations
∴ the solution will be choice (c)
c.] f(x) = – (x-2)² + 5
======================================================

problems (1),(2) can be solved by substituting with the model of data
at the general form the quadratic function:
F(x) = a (x+b)² + c
and solve to find a, b, c
OR, It is easier to use the graph to find the appropriate quadratic equation
as  we did previously
=========================================================

(3)
      h(t) = - 12t² + 36t.
      when the object hits the ground ⇒⇒ h = 0
∴   - 12t² + 36t = 0              ⇒⇒ factor t
∴  t ( -12t +36 ) = 0
t = 0 (unacceptable)    OR   t = 36/12 = 3 sec.

∴ the solution will be choice (c)
=======================================================

(4)
    h(t) = - 8t² + 32t
At maximum height  ⇒⇒⇒      dh/dt = 0
∴ dh/dt = -16t +32 = 0
∴ t = 32/16 = 2 sec.

∴ the solution will be choice (b)

The vertex of the quadratic function is (1.5, -.75)
