answer the questions below

Section 2.8: Problem 1 (1 point) The linear approximation at z = 0 to f(z) = 1 V2 - x is L(x) = A + Bx where A = B = Section 2.8: Problem 2 (1 point) Use linear approximation, i.e, the tangent line, to approximate v 64.1 as follows: Let f(z) = vi. The equation of the tangent line in slope-intercept form to f(x) at a = 64 can be written in the form y = mz + b where: m = b Using this, we find our approximation for v 64.1 is NOTE: For this last part, give your answer to at least 6 significant figures or use fractions to give the exact answer. Section 2.8: Problem 3 (1 point) Use linear approximation, le. the tangent line, to approximate 0.254 as follows: Let f(x) = - and find the equation of the tangent line in slope-intercept form to f(x) at a "nice" point near 0.254. Then use this to approximate 0.254
