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 :

To solve this question, we need to understand what the function [tex]\( C(F) = \frac{5}{9}(F-32) \)[/tex] does. This function is used to convert temperatures from degrees Fahrenheit to degrees Celsius. Here's how to interpret the function:

1. Identify the Function Inputs and Outputs:
- The input of the function is [tex]\( F \)[/tex], which represents a temperature in degrees Fahrenheit.
- The output of the function, [tex]\( C(F) \)[/tex], represents the corresponding temperature in degrees Celsius after the conversion.

2. Understanding the Conversion Formula:
- The formula [tex]\( C(F) = \frac{5}{9}(F-32) \)[/tex] is the standard formula to convert Fahrenheit to Celsius.

3. Analyze What [tex]\( C(F) \)[/tex] Stands For:
- [tex]\( C(F) \)[/tex] is the result after applying the formula to convert from Fahrenheit to Celsius. Therefore, [tex]\( C(F) \)[/tex] represents the temperature in degrees Celsius.

Given this breakdown:

- The correct interpretation is that [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.

So, 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.
