<ul><li> Polynomial Curve Sketching </li> <li> Warm up When the polynomial 2x2 + bx - 5 is divided by x - 3, the remainder is 7. (a) Determine the value of b. </li> <li> Warm up Solve by factoring the polynomial completely. (a) x 3 + 5x 2 + 2x - 8 = 0 </li> <li> Use your TI 83 to find the roots of the polynomial. x3 - 2x2 - 5x + 6 Answer x = -2, 1, 3 </li> <li> Degree n of a polynomial is odd The function has opposite behaviour If the leading coefficient is &gt;0 The graph rises to the right and falls to the left 3 2 x +2x +1 If the leading coefficient is 0 the graph rises on the left and rises on the right 4 3 2 x + x - 2x + x + 1 If the leading coefficient</li></ul>
