Determine the intervals of the domain over which the function is continuous.

Solution

1)

you can take any value in \"x\", the the answer is the letter (D)

2)

you can\'t take x = 1 because it is indeterminate, so the interval is: (-INF,1) U (1,INF)

So the correct answer is the letter (C)

3)

4)

you can take any value in \"x\", the the answer is the letter (C)
