Please solve problem 8 with reference to problem 4

Problem 4. Consider the inner product space C[-1, 1] with the inner product defined by
(f,g) =
f(x)g(x) dx
and the induced norm. Find the best least squares approximation to the function f(x) = x¹/³
on [-1, 1] by a linear function ((x) = ₁ + ₂x.
[Hint: first show that the functions h₁(x) = 1 and h₂(x) = x are orthogonal.]
