Hi, it's been awhile since I've been on here but I've now officially started Linear Algebra.
There are two problems in my homework I cannot solve. They are the following:
1. Find the equation of the form that passes through points and using elementary row operations on a matrix.
2. Find the equation of the parabola that pass through (0,3), (1,9) and (2,3) using elementary row operations on a matrix.
I believe I have the second problem solved but I am unsure of my answer. Thank you for looking at this! =)
