Question

1 EXCHANGE RATE. The Bangko Sentral ng Pilipinas reports international exchange rates each day. On September 2, 2020, the exchange rate for Philippine peso was 48.48. Therefore the formula that gives Philippine peso in terms of United States dollars on that day is P= 48.48D where P represents Philippine peso and D represents United States dollars Find the inverse of the function to determine the value of a United States dollar in terms of Philippine on September 2, 2020​

Answer 1

Answer:

Under a market‐determined exchange rate framework, the BSP does not set the foreign exchange rate but instead allows the value of the peso to be determined by the supply of and demand for foreign exchange. ... On such occasions of excessive movements, the BSP enters the market mainly to maintain order and stability.

Answer 2

inverse function g(D) = 0.0206D

Explanation:

• An inverse function is a function that returns the original value for which a function provided the output.
• If f(x) returns the value y, f-1(y) is the inverse function that returns the value x.

                                                                                                       

                     $We \ have\\\\1 Dollar = 48.48 peso\\\\we \ need \ a \ function \ that \ will \ return \\\\value \ of \ dollar \ from \ peso \ \\\\\therefore f(D) = 48.48D\\\\\implies g(D) = f^-^1(D) = \frac{1}{48.48} D = 0.0206270627D \approx 0.0206D$
