07. The major advantage of the NewtonRaphson method is a. No need for initial approximation to the root. b. Robustness. c. Speed and ability to solve systems of equations.

08. Function C = polyfit ( X, Y, 2 ) returns array of coefficients C of a fitting polynomial

a. b. c. f(x)= C[1]x2+C[2] f(x) = C[31x2 + C[2]x + C[1] f(x) = C[1]x2 + C[2]x + C[3]
