f(x)=x-2

(x^2)-3x+2

or (x-2)/((x^2)-3x+2)

1. Find the domain and range of f

2. Find the lim x-->1 f(x)

3. Find the lim x-->2 f(x)

4. Apply the definition of continuity to identify any points of discontinuity

Show all work or explain why the lim does not exist.

I think the limit x-->1 f(x) is infinite and lim-->2 f(x) is 1, but not 100% sure since i feel i'm doing this wrong. Help??
