Question 2: A function S is defined on the interval [(-1,3] by S₁(x), x[-1,0), S(x) = S2(x), x[0, 2), S3(2), x = a € [2,3, where S1, S2 and S3 are cubic polynomials. Write down the system of twelve equations that must be satisfied if S is a natural cubic spline interpolating the function defined by equations f(x1)=-3, f(x2) = 1 f(x3) = -3 and f(x4) = 1, where x1 -1, x2 = 0, x3 = 2 and x4 = 3. = 3 11 - If S₁(x) = − ³½³√(x + 1)³ + 2 2 9 (5) (x+1)3 and S3(x) = − 3√(x − 2) ³ + √(x − 2)² + (x − 2) — 3, - use some of the constraints derived above to determine S2(x).
