Don't know if this will help but if you cut it from corner to corner it will make a triangle
The answer is C i think though
The inverse function
is such that

If
, then we have

Solve for the inverse :

Answer:
Option C: -$1500 is the correct answer.
Step-by-step explanation:
Given that:
Total amount invested in business = $24,000
Loss suffered in first quarter = $4500
As the amount is shared by Brian, Steve and Rita equally, therefore,
