Homework Equations
Solve using limits. Function is continuous if it's graph is continuous throughout. here the (x-1) term gets canceled in numerator and denominator. So we have a continuous graph of (x+1).
The Attempt at a Solution
The (x-1) term gets canceled from numerator and denominator and we get a continuous function (x+1) which is defined everywhere.
It is also differentiable with derivative of (x+1) = 1.
So answer is D.
Book answer is C. How?
