In the attached diagram you can see the graph of the function 
As you can see graph is:
1. increasing from x = −2 to x = −1
2. decreasing from x = 0 to x = 1
3. decreasing and then increasing from x=1 to x=2
4. increasing from x=2 to x=4.
Answer: correct choice is B.
Answer: 1. ∠A= 80.75° 2. 41.79 
Step-by-step explanation:
Since, According to the sines low,

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

⇒ 
⇒ 
⇒ A = 80.75°
2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1
=34.86 + 6.93
= 41.79 square cm
It causes the breakdown and decay to the rocks. It occurs when the weather water is slightly acidic.
