rational function – Solved Problems

Problem 2-9: Differentiating Polynomial and Rational Functions

Differentiating f(x)= 1+ 2x, f(x)= 1 – 2x + 2x^2, f(x)= 1- x^2 +1/x and f(x)= 1 – x +1/(1-x)

Problem 2-4: Computing Limits of a Rational Function

Computing Limits of (x^2+2x-3)/(x+3) as x approaches -3 and 3. The case for x ->-3 is an indeterminated form and algebraic elimination is used to solve it.
