Question

A person can burn about 7 calories per minute bicycling. Let x represent the number of minutes bicycled,
and let y represent the number of calories burned. Create a mapping diagram to show the number of
calories burned by bicycling for 40, 80, 120, or 160 minutes. Determine the domain and range of the
relation in context and explain whether or not this represents a function.

Answer 1

Answer:

Minutes  Calories

50                    350

100                   700

150                   1050

200                  1400

The domain values are

50, 100, 150, 200

The domain is minutes bicycling

.

The range values are

350, 700, 1050, 1400

The range is the calories burned

.

This relation is a function. Each domain value is paired with exactly one range value

Step-by-step explanation:

Since the person burns 7 calories per minute, multiply the number of minutes by 7 to find the range.
