Use linear approximation to approximate v 49.1 as follows. ms Let f(x) = vx. The equation of the tangent line to f (x) at x = 49 can be written in the form y = ma + b. Compute m and b. m = b = Using this find the approximation for \\ 49.1. Answer:Find the linear approximation of f(a ) = In x at x = 1 and use it to estimate In (1.25). L(a) In 1.25 ~Use linear approximation to approximate v 25.2 as follows. Let f(x) = Vx. The equation of the tangent line to f (x) at x = 25 can be written in the form y = ma + b. Compute m and b. m b Using this find the approximation for \\ 25.2
