Method1:parabola
y = x^2 - 2x + 8
y-7 = (x-1)^2 ; parabola
turning point is (1,7)
method2:diff
y = x^2 - 2x + 8
y' = 2x -2 = 0 ==> x = 1,
y=7

72/9 = 8
9 (w + 8)
The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
