Question

Water is being drained out of a 50 -gallon water heater tank at a rate of 10gallon(s)/(m)in. The process continues until the tank is empty. The function that models this situation is f(x)=50-10x, where f(x) represents the number of gallons of water remaining in the tank after x min. Which statements are true about the domain and range of the function for this situation? Select TWO correct answers

Answer 1

There are no options shown.

explenation of the range and domain:

The domain is 0 ≤ x ≤ 5

the tank cannot have a negative storage, and the time starts at 0

for x = 0, there is 50 gallon, and on x=5, there is 0 gallon left.

so the range is from 0 to and including 50
