The following 3 points are on a parabola defining the edge of a ski (-4, 1), (-2, 0.94), (0.1)
The general form for the equation of a parabola is:

Ax^2+ Bx +C= y

Required:
a. Use the x- and y-values of 1 of the points to build a linear equation with 3 variables: A, B, and C.
b. Repeat this process with 1 of the other 2 points to build a 2nd linear equation.
c. Record your equation here. Repeat this process with the other point to build a 3rd equation.
