Web∇a(x,y) = (1,2y)(x,y), ∇h(x,y) = (2x,4y3)(x,y). The method of Lagrange multipliers indicates that we must solve the system, 1 = λ·2x, 2y = λ·4y3, x2 +y4 = 1. [3 points] From the first equation, we see that x ̸= 0, λ = 1 2x 0. For the second equation, we split into two cases: WebFirst, let's calculate f (8) using the function f (x): f (x) = 3x^3 - 2x + 7 f (8) = 3 (8)^3 - 2 (8) + 7 f (8) = 1535. Next, let's calculate h (8) using the function h (x): h (x) = x^2 - x + 1 h (8) = (8)^2 - 8 + 1 h (8) = 57. Now we can substitute these values into the equation f (8) = g (8)h (8) + r (8) and solve for g (8) and r (8).
