ONLINE OEd Video Tutorials For Problems 1 and 2, sketch the graph of the polynomial function. Interactive Exam 1. f( x) = x(x - 3) 2. (x) ( x + 1)( 4)( 2 10 ) For Problems 3 and 4, use technology to graph the polynomial function. Determine the x-intercepts, whether the graph crosses or is tangent to the x-axis at each x-intercept, the number of turning points, and the number and type (global, or local but not global) of any maximum or minimum values. 3. ((x) = -x(x+7)(x -4) 4. ((x) =(x - 5) (x+ 2)' For Problems 5 and 6, write a cubic or quartic function in intercept form for the given graph. Assume that all x-intercepts are integers and that the constant factor a is either'1 or -1. 5 360 9 8 180 Houghton Mifflin Harcourt Publishing Company 240 120 120 60 120 180
