Unformatted text preview: f has at least 8 roots in [2 , 2], or f has at most 6 roots in [2 , 2] . b) If f ( x ) = x 44 x 2 + 2, verify that the relevant values of f are given by the table above. Sketch the graph of y = f ( x ) in the viewing window [2 . 5 , 2 . 5] [3 , 3]. How many roots does f have in the interval [2 , 2]? Find the roots algebraically. Suggestion: Substitute t = x 2 . c) If f ( x ) = x 44 x 2 +2+5(2 x1) x ( x 21)( x 24), verify that the relevant values of f are given by the table above. Using the Intermediate Value Theorem nd as many roots of f in the interval [2 , 2] as possible. 1...
