Homework Statement
f(x) = -x + b, if x < 2
= 5, if x = 2
= -20/(x-b) + 1, if x > 2
For what value(s) of b does f have a removable discontinuity at 2?
For what value(s) of b does f have a (finite) jump discontinuity at 2? Write your answer in interval notation.
The Attempt at a Solution
I'm completely stumped on the removable discontinuity, because I thought you had to be able to cancel out the bottom?
And I'm not sure how to find a jump discontinuity.
