I need help with these 3 calculus questions:

Question 4 (1 point) The linear approximation of f(x) = In(x) at x = 1 is: OL(X) = x- 1 OL(X) = X OL(X) = x+1 OL(x) = 1 None of these options are correct.Question 5 (1 point) Use the linear approximation of f(x) = In(x) at x = 1 to estimate In(1.31). In(1.31) ~ 2.31 In(1.31) ~ 1.31 In(1.31) ~ 1.27 In(1.31) ~ 0.27 OIn(1.31) ~ 0.31Question 6 (1 point) Suppose f and g are functions with the following properties: f(2) = 570) = 0, f'(2) = f\"(2) = 2, g'(2) = g\"(2) = 1. If the second degree Taylor polynomial of y = f(x)g(x) about the point x = 2 is given by a0 + a1(x 2) + a2(x 2)2 then (12 is equal to which of the following
