High School

For one month, Siera calculated her hometown's average high temperature in degrees Fahrenheit. She wants to convert that temperature from degrees Fahrenheit to degrees Celsius using the function [tex]$C(F)=\frac{5}{9}(F-32)$[/tex]. What does [tex]$C(F)$[/tex] represent?

A. [tex]$C(F)$[/tex] represents the output of the function [tex]$C$[/tex] in degrees Celsius when the input [tex]$F$[/tex] is in degrees Fahrenheit.

B. [tex]$C(F)$[/tex] represents the output of the function [tex]$F$[/tex] in degrees Fahrenheit when the input [tex]$C$[/tex] is in degrees Celsius.

C. [tex]$C(F)$[/tex] represents the output of the function [tex]$C$[/tex] in degrees Fahrenheit when the input [tex]$F$[/tex] is in degrees Celsius.

D. [tex]$C(F)$[/tex] represents the output of the function [tex]$F$[/tex] in degrees Celsius when the input [tex]$C$[/tex] is in degrees Fahrenheit.

Answer :

Certainly! Let's break down the problem to understand it clearly.

You are given a function [tex]\( C(F) = \frac{5}{9}(F - 32) \)[/tex]. This function is used to convert a temperature from degrees Fahrenheit (F) to degrees Celsius (C).

Now, let’s understand what [tex]\( C(F) \)[/tex] represents:

- [tex]\( C(F) \)[/tex] is the notation of the function where [tex]\( C \)[/tex] is the output (or the result) when you input a value [tex]\( F \)[/tex].

- [tex]\( F \)[/tex] is the input value in degrees Fahrenheit.

- The function [tex]\( C(F) = \frac{5}{9}(F - 32) \)[/tex] calculates the temperature in degrees Celsius using the input temperature in degrees Fahrenheit.

Thus, when you interpret [tex]\( C(F) \)[/tex] in the context of the given function:

1. The function [tex]\( C \)[/tex]: This function converts temperatures from degrees Fahrenheit to degrees Celsius.

2. Input (F): This is the temperature value in degrees Fahrenheit.

3. Output [tex]\( C(F) \)[/tex]: This is the converted temperature value in degrees Celsius.

Based on this understanding, the correct interpretation is:

[tex]\( C(F) \)[/tex] represents the output of the function [tex]\( C \)[/tex] in degrees Celsius when the input [tex]\( F \)[/tex] is in degrees Fahrenheit.

Therefore, the correct choice is:

- [tex]\( C(F) \)[/tex] represents the output of the function [tex]\( C \)[/tex] in degrees Celsius when the input [tex]\( F \)[/tex] is in degrees Fahrenheit.
