Question 1 Use Newton's method to approximate a root of the equation 4x + 6x* + 2 = 0 as follows. Let x1 = 2 be the initial approximation. The second approximation 2 is and the third approximation 3 is (Although these are approximations of the root, enter exact expressions for each approximation.) Question Help: DVideo Use linear approximation, i.e. the tangent line, to approximate v 36.3 as follows: Let f(x) = v. Find the equation of the tangent line to f(x) at r = 36 L(x) = Using this, we find our approximation for v 36.3 is NOTE: For this part, give your answer to at least 9 significant figures or use an expression to give the exact answer.
