P(z) =a + a₁²
which gives the best least squares fit for the following points:
(-4,0), (-2,-2), (4,-9), (5,-8)
How to enter polynomials.
Enter the formula for a polynomial using * to denote multiplication and
^ to denote the exponent. For example, if the answer is the polynomial
3
P(x) = 1-2x + =z² +4.5x³
then you should enter 1 - 2*x + (3/7)*x^2 + 4.5*x^3.
