can you guys help me solve this problem?
ACTIVITY 3 NAME 1) A 1200-gallon tank initially contains 100 gallons of oil. A pump is filling the tank at a rate of 8 gallons per minute. a) Write a formula for the linear function f (x) that models the number of gallons of oil in the tank after x minutes. b) Identify the y-intercept and interpret it. c) Does the x-intercept of this function have any meaning in this problem? Explain! d) Graph your function. Be accurate and label the axes. (Hint: The tank will only hold 1200 gallons, so at what time will the tank be full?) e) What is the relevant omain for f(x)? f) What is the relevant range for f(x)?
