1. * 7 *5 Find the respective linear functions approximation f below for the choice of a = 3. Answers will be graded on a correct/incorrect basis only, in particular, no work needs to be shown. (a) 5 f(2) = 202 (b) = f (2) = 24 (c) 5 f(2) = 1 (d) 5 f(x) = Vac2+7 (e) 5 f(x) = sin(1 - ) (f) = f(x) = tan Ta
