okay so i am trying to model a cubic equation to fit my curve
my base curve is specifications:
x value0 to 6.19
amplitude0.77
amplitude coordinates3.73,0.77
x intercepts0,0 and 6.19 , 0
this is my curve and i have to make a equation and include transformations to make this equation ax3+bx2+cx fit that curve

x (x6.19) (x+a) = 0
when x = 3.73, y = .77
3.73 (3.736.19)(x+a) = .77
3.73 (2.46)(x+a) = .77
x+a =  .0949
a = .0949 call it .095
so
(x^26.19x)(x+.095) = 0
x^3 6.19x^2 +.095x  .587 = y
