I'm trying to work out the equation of a curve through 5 very specific points... these points are(adsbygoogle = window.adsbygoogle || []).push({});

(47.5, 46.3) (45,48.1) (43, 38.1) (40, 32.8) (37, 26.5)

Thought of having general equation ax^4+bx^3+cx^2+dx+e and subbing all the points in and solving but that would take way too long... If there is any simper way to do this or if you could post any link to a program capable of solving it quickly that'd be great.
