EXPLORE! Store the function in Example 2.3.2, y (2x 1)(2x2 x 1), into Y1 of the equation editor. Graph using the modified decimal window [ 2.35, 2.35]1 by [ 3.1, 3.1]1 and trace the cursor to X 1. Construct the tangent line to the curve at this point using the Tangent feature of the DRAW (2nd PRGM) key. Does the equation of the tangent agree with what is calculated in the example?
