A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes
Domain x is number of hours
Range y is distance traveled
speed = 12 miles per hour
time = 45 minutes = = 0.75 hours
We know distance formula
Distance = speed * time
Distance = 12 * 0.75= 9 miles
Number of hours x is 0 to 0.75 hours
So domain is { }
Distance is 0 to 9 miles
So range is { }
If 3y's greatest possible value is 30, that means 3y can't be greater than 30. So it has to be less than or equal to 30.
