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. the temperature of [tex]F[/tex] degrees Fahrenheit converted to degrees Celsius
B. the temperature of [tex]F[/tex] degrees Celsius converted to degrees Fahrenheit
C. the temperature of [tex]C[/tex] degrees Fahrenheit converted to degrees Celsius
D. the temperature of [tex]C[/tex] degrees Celsius converted to degrees Fahrenheit

Answer :

To answer the question, we need to understand what the function [tex]\( C(F) = \frac{5}{9}(F - 32) \)[/tex] represents.

Here’s a detailed breakdown:

1. Understanding the Variables:
- [tex]\( F \)[/tex]: This represents the temperature in degrees Fahrenheit.
- [tex]\( C(F) \)[/tex]: This corresponds to the temperature in degrees Celsius that is calculated from the temperature [tex]\( F \)[/tex] in degrees Fahrenheit.

2. Function Analysis:
- The equation [tex]\( C(F) = \frac{5}{9}(F - 32) \)[/tex] is a commonly used formula to convert temperatures from Fahrenheit to Celsius.

3. Conversion Context:
- The expression [tex]\( \frac{5}{9}(F - 32) \)[/tex] transforms a given Fahrenheit temperature [tex]\( F \)[/tex] into a temperature in degrees Celsius.

4. Correct Interpretation:
- Therefore, [tex]\( C(F) \)[/tex] represents the temperature of [tex]\( F \)[/tex] degrees Fahrenheit converted to degrees Celsius.

From the options given:
- Option 1: The temperature of [tex]\( F \)[/tex] degrees Fahrenheit converted to degrees Celsius – This is correct.
- Option 2: The temperature of [tex]\( F \)[/tex] degrees Celsius converted to degrees Fahrenheit – This is incorrect because [tex]\( F \)[/tex] should be in Fahrenheit.
- Option 3: The temperature of [tex]\( C \)[/tex] degrees Fahrenheit converted to degrees Celsius – This is incorrect because it refers to converting [tex]\( C \)[/tex] (which is Celsius in the function) back to Celsius.
- Option 4: The temperature of [tex]\( C \)[/tex] degrees Celsius converted to degrees Fahrenheit – This is incorrect as it refers to converting [tex]\( C \)[/tex] (Celsius) to Fahrenheit.

Therefore, the accurate statement is:
The temperature of [tex]\( F \)[/tex] degrees Fahrenheit converted to degrees Celsius.

This matches with Option 1.
