Question

The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation f = StartFraction 9 Over 5 EndFraction c + 32. Which statement best describes the relation (c, f)?

A. It is a function because –40°C is paired with –40°F.
B. It is a function because every Celsius temperature is associated with only one
Fahrenheit temperature.
C. It is not a function because 0°C is not paired with 0°F.
D. It is not a function because some Celsius temperatures cannot be associated with
a Fahrenheit temperature.

Answer 1

B

Explanation:

This is the answer because a function cannot have an x-value that produces more than one y-value.

The equation is in slope-intercept form (y = mx + b), where F is y and C is x.
