Question

What's the answer??(SOMEONE PLEASE HELP ME)

Answer 1

Given :

F(x) =
`(9)/(5)x + 32`

C(x) = x - 273.15

We know that :

If f(x) and g(x) are Two Functions Defined under same Domain, then Composite Function : (f o g)(x) = f(g(x))

The Question is to find a Composite Function that can be used to convert Temperatures from degrees kelvin to degrees Fahrenheit

⇒ The Final Answer should be in Fahrenheit

⇒ The Question is to Find the Value of (F o C)(x)

⇒ (F o C)(x) = F(C(x))

⇒
`(F\;o\;C)(x) = F(x - 273.15)`

⇒
`(F\;o\;C)(x) = (9)/(5)(x - 273.15) + 32`

Last Option is the Answer
