Answer:
C
Step-by-step explanation:
The table shows the sign of the function is the opposite of the sign of x, so ...
as x → ∞, f(x) → -∞; as x → -∞, f(x) → ∞ . . . . . matches the 3rd choice
Answer:

Step-by-step explanation:
Find the area of the square - area of 4 sectors
We'll use the formula to find one sector area

where r is the radius of one sector and x is the angle in radians
Since each angle is in a square, the angle of the sectors is 90 degrees.
Convert degrees to radians

The radius of one sector is given by 70mm/2=35mm
One sector area:

Area of all 4 sectors:

Area of the square:

Hence, Area of square - 4 Sectors:
