graph of limit functions

1. Sketch a graph of a function that satisfies all of the following conditions:

1. f (3)=4
2. limx--->3 f (x)=-1
3. limx--->-2 f (x) does not exist.
4. limx--->-2- f (x)=4

2. Sketch a graph of a function that satisfies all of the following conditions:

1. limx---> -1 f (x)=3
2. f is discontinuous at -1
3. the domain of f is (- infinity, + infinity)
4. limx--->- infinity f (x) = 5
5. limx--->infinity f (x)= 0

3. Sketch a graph of a function that satisfies all of the following conditions:

2. f has a removable discontinuity at 3.
3. f (3)=4
4. limx---> infinity f (x) =/(not equal to) +- infinity
5. f has no horizontal asymptotes
