Question 4 In this problem we consider f(x)=√ near x = 16. (a) Find L(r), the linear approximation of f(x) for r near 16. (b) Use L(a) to approximate f(16.1) and f(16.01). (c) Recall that if f is twice differentiable lim 2 f"(a). Therefore, this means that |f" \/" (a) (Ax)², where Az = x-a as usual. With this in mind, what do you think approximately happens to the error when Ar is made ten times smaller? One hundred times smaller? f(x) - L(a) (x-a)² (size of error from approximating f(x)=L(x)) = f(x) - L(x)|≈! (d) Use a calculator to find the errors f(16.1) - L(16.1)| and f(16.01) - L(16.01). Is this consistent with your prediction in the previous part? (e) Find Q(x), the quadratic approximation of f(a) for a near 16. (f) Use Q(x) to approximate f(16.1) and f(16.01). f(x) - Q(x) (g) Use a calculator to find the errors |f(16.1) - Q(16.1)| and f(16.01) - Q(16.01). Note: If f is three times differentiable, then lim Therefore, the size of the quadratic (Ax)³ proportional to Ar]³, with constant related to the third Az-0 6 approximation error is approximately derivative!
