"Using matrix methods, find a quadratic function and a cubic function which model this situation (the data points). Explain the process you used."

The Data points are:

Guide number (from tip) 1, 2, 3, 4, 5, 6, 7, 8
Distance from tip (cm) 10, 23, 38, 55, 74, 96, 120, 149

I have no idea how to make a quadratic/cubic function using matrices, please help!
