Question: b(x) = - .007x^2 - 1.25x + 200 c(x) = .11x^3 - 1.9x^2 + 9.4x + 26 PART C 1. On your graphing calculator, graph

b(x) = - .007x^2 - 1.25x + 200

c(x) = .11x^3 - 1.9x^2 + 9.4x + 26

PART C 1. On your graphing calculator, graph b(x) and c(x) at the same time. Use the window settings of: XMIN = 0; XMAX = 125; YMIN=0; YMAX=300. You should notice that the graphs of the functions intersect. The intersection point is: (16.99, 176.74). Since the graphs intersect at that point, does this mean that in that year, there were the same number of blacksmiths and computer support specialists? Explain your reasoning. If there are years where these careers have equal numbers, list those years. (Use maximums, minimums, intercepts, if needed to help explain.)

2. If you needed to illustrate the trends of both of these careers, how could you display the graphs of the functions effectively to compare and contrast the trends? Is it appropriate to show the graphs of these two functions at the same time, in the same coordinate system? Explain or illustrate an effective way to compare the graphs and their trends.
