Question
The function f(x) is defined by f(x) = 
Options
A.is continuous at x = 1
B.is discontinuous at x = 1 since f(1+) does not exist though f(1-) exists
C.is discontinuous at x = 1 since f(1-) does not exist though f(1+) exists
D.is discontinuous since neither f(1-) nor f(1+) exists.
Solution
f(x) =
f(1 - h) = 
does not exist as denominater is tending to zero.
similarly
f(x) also does not exist. Create a free account to view solution
