Question

The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation mc026-1.jpg. Which statement best describes the relation (c, f)? It is a function because –40°C is paired with –40°F. It is a function because every Celsius temperature is associated with only one Fahrenheit temperature. It is not a function because 0°C is not paired with 0°F. It is not a function because some Celsius temperatures cannot be associated with a Fahrenheit temperature.

Answer 1

Answer 2

The correct answer is that it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.

Step-by-step explanation:
In this equation, degrees Celsius (c) is the independent variable and degrees Fahrenheit (f) is the dependent variable. This means all of our values of c will be the domain and our values of f will be the range. The definition of a function is a relation in which each element of the domain is mapped to only one element of the range; this means each Celsius temperature must be associated with only one Fahrenheit temperature. This is true, so this is a function.
