for 1. a and 1. c, i just addressed a problem a problem here that might help. see posts #8 and #10.

for 1. b, there seems to be a typo or something. what does that | in front of the 2 mean?

what do you mean by the "argument" of the functions?1. b Find the argument of these functions:

and

hint: what does the function look like? when x gets large, what happens? does adding 1 change the function much?1. c Find the limits:

lim and lim

x->infinity x->-infinity

another hint: negative powers mean we take the reciprocal of the function. so, for instance, . use this as a hint for the limit as

still don't know what you mean here1. d Does the functionany arguments ?

hint: recall what a "hole" is2. a The functionis not conjoined in two specific points (x,y). Which points are they and why ?

did you find all the points where the function is discontinuous? did you find the vertical asymptotes and holes?

2. b Can you find any answer for f(x) in these points noted before so the function becomes conjoined and if so, which points are they. And if not, how come ?
