The tangent equation of the curve y = X3 + X-2 parallel to the straight line y = 4x-1 is () A. 4x-y = 0b. 4x-y-4 = 0C. 4x-y-2 = 0d. 4x-y = 0 or 4x-y-4 = 0

The tangent equation of the curve y = X3 + X-2 parallel to the straight line y = 4x-1 is () A. 4x-y = 0b. 4x-y-4 = 0C. 4x-y-2 = 0d. 4x-y = 0 or 4x-y-4 = 0

If the tangent point is (a, b), then 3a2 + 1 = 4, the solution is a = 1 or a = - 1, the tangent point is (1, 0) or (- 1, - 4), which is parallel to the straight line 4x-y-1 = 0 and tangent to the curve y = X3 + X-2. The linear equation is 4x-y-4 = 0 and 4x-y = 0, so D is selected
