Consider the following graph of a function F

F(x) =

1/x --> x < -1

2 --> -1 (less than or equal to) x < 1

3 --> x = 1

x+1 --> 1 < x (less than or equal to) 2

-1/(x-2) --> 2 < x

(a) Find lim x-->1- F(X)

(b) Find lim x-->-1+ F(X)

(c) Find lim x-->-1 F(X)

(d) Find lim x-->1 F(X)

(e) Is F continuous at x=1

this is what i got for the answers

(a) 1/x

(b) 2

(c) 2

(d) none

(e) no

are these answer correct?
