Homework Help: calculus

Posted by allison on Thursday, September 24, 2009 at 10:32pm.

I have a couple of questions that I'm not sure how to do!

1) Given f(x) = (x^2 - 2x + 1) for x does not equal 1 and (k) for x = 1

Determine the value of k for which f is continuous for all real x.

a) 0
b) 1
e)none of the above

i think the anser is a but i'm really not sure how to solve this.

2) The graph of y = sinx / x has

I. a vertical asymptote at x=0
II. a horizontal asymptote at y=0
III. an infinite number of zeros

a) I only
b) II only
c) III only
d) I and II only
e) II and III only

I think the answer is d but I'm not positive.

If someone could please help me that would be greatly appreciated! :)
