The correct answer is B)
-3 < y ≤ 3
You can tell this by looking at the graph. The lowest that it goes is -3. You'll also note that the -3 has an open circle, which means that it isn't includes and thus needs a <.
The highest it goes it 3. You'll note that it has a closed circle, which means it is included and needs a ≤.
Number = 42
Percent increase = 50%
Increase in number = 50% of 42
= 50/100 × 42 =21
So, increased number = 42+21 = 63
