Not sure what BiQuad is, but if you want to fit a parabola through those three points, you have, assuming that
v(t) = at^2 + bt + c,
0a+0b+c = 10000
9a+3b+c = 2025
36a+6b+c = 6400
Somehow I suspect what you really wanted was v(3) = 1000-2025 = 7975, since most stocks don't bounce like that.
At any rate, solve for a,b,c for your model:
clearly, c=10000
Now just find a and b.
(a).Time (t) 0 weeks 3 weeks 6weeks
Investment Value v(t) $10000 $2025 $6400
Using the data written down in the table in (a) derive a quadratic function (you BiQuad model), 𝑣(𝑡), relating the value of Peter’s share portfolio to elapsed time. Show all working.
