The required graph is decreasing in -1 <x <0 and 0 < x < 1. Options b and c are correct.
Given that,
A graph of the function is shown it the domain at which the function is decreasing is to be determined.
What is a domain?
The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.
Here,
Since in the initial stage, the function is increasing, from -3 < x < -1 after that function starts decreasing from -1 < x < 1 and afterward again increasing,
Thus, The required graph is decreasing in -1 <x <0 and 0 < x < 1. Options b and c are correct.
