Round coefficients in your answer to 1 decimal place. Find the least squares approximation g(x) = a0 a1x a2x2 of the function f, and use a graphing utility to graph f and g in the same viewing window. f(x) = 2x3, 0 ≤ x ≤ 1 (a) Find the least squares approximation g(x) = a0 a1x a2x2 of the function f. g(x) =
