Display the graphs of y = - 5x and its derivative on a graphing calculator. State any conclusions you can draw from the relationship of the two graphs. Choose the correct display of y = - 5x and its derivative. Each graph is displayed in a viewing window [-5,5,1] by [-5,5, 1]. O A. OB. O C. OD. Choose the best conclusion below. O A. The slope of - is increasing. Furthermore, since x is never negative, the slope of - will always be positive. dx O B. The slope of is constant. Furthermore, since x is never negative, the slope of - will always be positive. O C. The slope of is decreasing. Furthermore, since - 5 is less than zero, the slope of y will always be decreasing. O D. The slope of - is constant. Furthermore, since - 5 is less than zero, the slope of y will always be decreasing. dx
