Answer the following: Show your solution below:

a. Use graphing platform to graph the function and determine the one-sided limit of this equation below.

Lim x-> 1- x + x + 1 x - 1

b. Find the limits:

Lim x-> 1* f(x) where f(x) = {x, XS 1 and 1 - X,X> 1}

Lim x-> 2* f(x) where f(x) = {x, XS 1 and 1 -x, x>1}
