Detailed solution thank you

et f be a function defined by f (x) = In(3 - 2x). a) (a.) Using the first 5 terms of the Maclaurin expansion of f. Approximate In (0.5) upto three-decimal place value. b) (b.) Using the first 4 terms of the Taylor series expansion of f about a = 1, approxi- mate the definite integral .2 f (20 ) dx. 1 x - 1
