1. Use gauss-jordan elimination to solve the following systems
x - 2y + z = -6
2x - 3y = 7
-x + 3y - 3z =11
I got a finite solution for this one which was wrong so I'm redoing it. Is it suppose to be infinite?
Ok. so I got x-3z=4
Now im stuck.
2. Determine the polynomial function whose graph passes through the points: (1,4), (2,0), (3,12)
This one i'm stuck on. Curve fitting?
