Question

last monday, the snow fell at a rate of 3 feet per hour for 7 hours. let y be the amount, of time x, in hours. this situation can be modeled by a function. identity the domain of the function

Answer 1

The domain of the function modeling the snowfall last Monday, where the snow fell at a rate of 3 feet per hour for 7 hours, is [0, 7].

Step-by-step explanation:

Last Monday, the snow fell at a rate of 3 feet per hour for 7 hours. In this scenario, the amount of snow y depends on the time x, in hours. This situation can be modeled by a linear function y = 3x, where y is the total snowfall and x is the number of hours.

The domain of the function is the set of all possible values of x that can be input into the function. Since the snow fell for 7 hours, the domain of this function would be all the hours during the snowfall, from 0 to 7, including 0 and 7. Thus, the domain is [0, 7].
