The equation of the tangent line y + 0.64 = - 1. 6 ( x + 0.8 ) * = - 0.64- 1. 6x -B/. 28 y= x2, point x = - 0.8 y! = 2x at x = -0.8 y1 = 2x ( -0.8 ) = -1.6 y ( 0.8) = (- 0. 8) 2= 0.64 ". The equation of the tangent line * - 0 .64 = - 1.6 ( x- (-0.8) ) y = 0. 64 - 1. EX - 1.28 = 1 - 1.6x-0-64 Where Writing Begin
