14. A tank is being filled with water. The function represents the height of the water in the tank, in feet, based on x, the amount of time in hours. Graph the function over a period of 5 hours on the coordinate plane below. Use appropriate scales on the x- and y-axes and be sure to label the graph. Is the function increasing or decreasing? What is the rate of change? Use words, numbers, and/or pictures to show your work. 15. Use the function graphed on the coordinate plane below. What are the intervals where the function is decreasing and increasing?
