Question

To convert temperatures from degrees Celsius to degrees Fahrenheit, you can use the function F(x)=9/5x+32 where x is the temperature in degrees Celsius. To convert temperatures from degrees Kelvin to degrees Celsius, you can use the function C(x)=x-273.15, where x is the temperature in degrees Kelvin. Find the composite function that can be used to convert temperatures from degrees Kelvin to degrees Fahrenheit.


(C * F)(x)=9/5x - 241.15
(F * C)(x)=9/5x - 241.15
(C * F)(x)=9/5(x-273.15)+32
(F * C)(x)=9/5(x-273.15)+32

Function wise, I know that it's either the third or fourth option, I just don't know if it's (C*F) or (F*C). Please help? Thanks

Answer 1

starting with Kelvin and going to Fahrenheit

Kelvin feeds into C(x)

C(x) feeds into F(x)

sometimes written as ... F(C(x))

F of C of x

Answer 2

Okay, thanks Scott:)
