Use a graphing calculator to approximate the critical numbers of f(x) to two decimal places. Find the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema. f(x)=x² - 4x³ +7x Approximate the critical numbers of f(x). Choose the correct answer below. A. x=-0.69, x=0.92, x= 4.69 B. x=-0.69, x=0.92, x=2.77, x=4.69 C. x=-0.69, x=0.92 D. x= -0.69, x=0.92, x=2.77
