Answer 1

@amistre64

Answer 2

we have 4 reference points, what do you consider we can do with them?

Answer 3

4 equations, with 4 unknowns ... can we do matrix stuff yet?

Answer 4

ax^2 + bx +c ?

Answer 5

thats only 3 unknowns :) lets go another degree

Answer 6

oooohhhh ax^3 +bx^2+cx

Answer 7

ax^3 + bx^2 + cx + d = y

Answer 8

but yeah, since 0,0, then d=0 by default

Answer 9

so then
