Answer:
The answer to your question is: I agree with you, the first option
Step-by-step explanation:
• (0,1) U (1,infinity) This is the right answer because there are 2 invervals in which the graph decreases, and these intervals are listed in this option.
•(-infinity,-1)U(-1,0) This option is wrong because from (-∞ , -1) the graph grows up and also from (-1, 0).
•(-infinity,-1) The graph grows up, this option is incorrect
. (1,infinity) The graph decreases but the option is incomplete.
