Use linear approximation, i.e. the tangent line, to approximate v 64.3 as follows: Let f(x) = C. Find the equation of the tangent line to f(@) at x = 64 L(x) Using this, we find our approximation for v64.3 is NOTE: For this part, give your answer to at least 9 significant figures or use an expression to give the exact answer.
