(Recall that water weighs 8.345 pounds per gallon.) a. If 24 pounds of water have drained from the tank, how many gallons of water are remaining in the tank? 10.124 gallons Preview b. Define a function f that determines the number of gallons of water in the tank, f(w), in terms of the number of pounds of water that have drained from the tank since the tank started draining, w. f(w) = 13-w/8.345 Preview c. What is the domain of f? Enter your answer as an interval. W Preview W: invalid interval notation d. What is the range of f? Enter your answer as an interval. Preview Box 1: Enter your answer as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 213, 5+4) Enter DNE for Does Not Exist, oo for Infinity Box 2: Enter your answer as an expression. Example: 3x 2+1, x/5, (a+b)/c Be sure your variables match those in the question Box 3: Enter your answer using interval notation. Example: [2,5) Use U for union to combine intervals.

Evaluate f(2). f (2) = 3 Preview b. What is the vertical intercept of f? (0,2) Preview c. Solve f(x) = 2 for x. Professor Lapan's Helpful Hint: You may need to find the equation of this line (or its constant rate of change) using parts a and b to solve for x precisely in part c if your estimation from the graph is not precise enough. x = -3 Preview d.
