Slide2

What is the Inverse Function and how is it applied with currency?

The Inverse Function is a function used to return a value from x to y. For example:

Function: F(X) = Y

Inverse Function: F^-1(Y)=X

The Inverse Function will get back the input (x) from the output (y) and vice versa.

I’ll be applying the Inverse function to real life situations such as knowing how currency is measured around the world in different areas.

Slide3

Currency in Japan

As of April 2019, the currency in Japan called Yen is valued at $0.90 US Dollars. How to apply the inverse function to this currency?

F(X)=Yen to USD: Yen = 0.90 USD, => Yen/0.90 = USD, For 1$ Value: 1 / 0.90 = USD, => $1.11 USD.

F^-1(x)=USD to Yen: USD = 1.11 Yen, => USD/1.11 = Yen, For $1 Value: 1 / 1.11 = Yen, => $0.90 Yen.

Slide4

Currency in Germany

As of April 2019, the currency of Germany called Euro is valued at $1.12 US Dollars. How to apply the inverse function to this currency?

F(X)= Euro to USD: EU = 1.12 USD, => EU / 1.12 = USD, For $1 Value: 1 / 1.12 = USD, => $0.89 USD.

F^-1(X)= USD to Euro: USD= 0.89 EU, => USD / 0.89 = EU, For $1 Value: 1 / 0.89 = EU, => $1.12 Euro

Slide5

Currency in Sweden

As of April 2019, the currency of Sweden called Krona is valued at $0.11 US Dollars. How to apply the inverse function to this currency?

F(x)= Krona to USD: KNA = 0.11 USD, KNA / 0.11 = USD, For 1$ Value: 1 / 0.11 = USD, => $9.09 USD.

F^-1(x)= USD to Krona: USD= 9.09 KNA, USD / 9.09 = KNA, For 1$ Value: 1 / 9.09 = KNA, => $0.11 Krona.

Slide6

Inverse Functions to determine distance while traveling.

An inverse function can be used to approximate distance and times traveling around the world.

Function: F(x)=(m)(x); m = miles per hour traveled, and x = hours it would take. This function approximate how far i've been traveling going one steady pace.

Inverse Function: F^-1(x)= x/m. This function tells me how long I have been traveling based on how far i've gotten.

Slide7

Traveling to Boston ( from City Tech)

F(x)=(m)(x); m = miles per hour traveled, and x = hours it would take.

F(x) = (60)(3.75)

F(x) = 225 miles

Which means driving at 60 miles per hour for 3.75 hours it would take 225 miles to get to Boston.

F^-1(x)= x/m

F(x) = 225/60

F(x) = 3.75 hours traveled

Which means after driving 225 miles at 60 miles per hour it would take 3.75 hours to get to Boston.

Slide8

Traveling to Bali (from NYC)

F(x)=(m)(x); m = miles per hour traveled, and x = hours it would take.

F(x) = (510)(21)

F(x) = 10,710 miles

Which means flying at 510 miles per hour for 21 hours it would take 10,710 miles to get to Bali.

F^-1(x)= x/m

F(x) = 10,710/510

F(x) = 21 hours traveled

Which means after flying for 10,710 miles at 510 miles per hour it would take 21 hours to get to Bali.

Slide9

Using Inverse Functions to find how much a piece of land is

An inverse function can be used to find how much a piece of land will be.

Function: F(x)=(s)(x)

Inverse Function:f^-1(x)=x/s

X= amount of square feet

S= base cost of square feet

These functions will help me find how much a piece of land is.

Slide10

Buying 300 square feet of land

F(x)=(s)(x)

F(x)=(30)(300)

F(x)= $9000

Buying 300 square feet of land costs $9000

F^-1(x)=9000/30

F^-1(x)=300 sq

$9000 can buy 300 square feet of land

Slide11

Buying 500 square feet of land

F(x)=(s)(x)

F(x)=(70)(500)

F(x)=35,000

Buying 500 square feet of land costs $35,000

F^-1(x)=35,000/70

F^-1(x)=500

$35,000 can buy 500 square feet of land Rafael 3
