Answer: B. ( -∞ , 0) and C. (1, 2)
<u>Step-by-step explanation:</u>
The y-value is increasing between x = -∞ and x = 0.
The y-value is decreasing between x = 0 and x = 1.
The y-value is increasing between x = 1 and x = 2.
The y-value is decreasing between x = 2 and x = +∞
So, the y-value is increasing at ( -∞ , 0) ∪ (1, 2)
