Given:
There is a graph given in the question
Required:
We need to find that which of the given options are correct
Step-by-step explanation:
1st As we can see that x=1 is holo dot so x=1 is not in the the domain
Correct
2nd By the graph if we see that the point (-1,0), it is clear that if x=-1, y=0
Correct
3rd The value of x=1 is not in domain so we can not tell anything about x=1
Not possible
4th We can see that there is holo dot so at the value of x=1 function is discontinuous
Correct
5th We get the value of y=0 when x=-1 so the function is not discontinuous
Not possible
6th As we can see that we can never get y negative
Correct
Final answer:
1st, 2nd, 4th, 6th are true
