all kinds of functions.
Any 3 non-collinear points can be expressed by a quadratic, a cubic, a trig function ....
e.g Wolfram found:
y = -4.7632sinx + 8.70749cosx - 7.70749
if you want a quadratic"
y = ax^2 + bx + c
-7 = 4a - 2b + c
1 = c
-17 = 9a + 3b + c
solve for a, b, and c
Which function contains this set of ordered pairs?
{(–2, –7), (0, 1), ( 3, –17)}
