Find a polynomial P(z) = a + a₂z+ª₂x² of degree 2 which gives the best least squares fit for the following points: (-3,32), (-1,13), (1,14), (5,35) 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(z) = 1-2x+z²+4.52³ then you should enter 1 - 2*x + (3/7)*x^2 + 4.5*x^3. Do not forget to use for multiplication! 35- 30- 25 20 15 10- 0 Note. You can enter polynomial coefficients either as fractions or in the decimal form, with precision up to 3 decimal places. Enter your answer:
