I will find the inverse function of f(n) to see if it is g(n).
![y - 2 = \sqrt[3]{\dfrac{x}{2}}](https://tex.z-dn.net/?f=%20y%20-%202%20%3D%20%5Csqrt%5B3%5D%7B%5Cdfrac%7Bx%7D%7B2%7D%7D%20)

![g(n) = \dfrac{\sqrt[3]{4n}} {2} + 2](https://tex.z-dn.net/?f=%20g%28n%29%20%3D%20%5Cdfrac%7B%5Csqrt%5B3%5D%7B4n%7D%7D%20%7B2%7D%20%2B%202%20)
The inverse function of f(n) is indeed g(n), so f(n) and g(n) are inverse functions.

Answer:
area of the sector = 3.25π yard²
Step-by-step explanation:
The radius of the circle is 3 yards . The central angle is 130° let us say it is the sector angle of the circle. The angle is 130°. If the shaded area of the circle is the sector area of the circle the area of the sector can be computed below.
area of a sector = ∅/360 × πr²
where
∅ = center angle
r = radius
area of the sector = 130/360 × π × 9
area of the sector = 1170π/360
area of the sector = 3.25π yard²
If the shaded area is segment. The shaded area can be solved with the formula.
Area of segment = area of sector - area of the triangle
Area of segment = ∅/360 × πr² - 1/2 sin∅ r²
The picture demonstrate the area of sector and the segment of a circle with illustration on how to compute the area of the triangle
