3) You wrote a function f(D) for the new yacht (problem 2b). The function gives the value of the expression on the left side of the America’s Cup rule for any displacement D. Use a graphing calculator (Desmos) to graph this function. Select all of the following that are true. Explain your reasoning. a) For any viewing window, the graph of f(D) lies entirely above the x-axis.
b) In the context of this real-world situation, the relevant domain of the function is all real numbers.
c) As the value of D increases, the value of f(D) decreases.
d) The graph of the function intersects the horizontal line y = 24 at exactly one point.
e) The graph shows that when D = 10, f(D) is less than 24.
f) The graph shows that a displacement of 30 cubic meters is one possible displacement for the new yacht.
