If the function f (x) = 13x3 + 12F ′ (1) x2-f ′ (2) x + 3, then the inclination angle of the tangent of F (x) at the point (0, f (0)) is () A. π4B. π3C. 2π3D. 34π

If the function f (x) = 13x3 + 12F ′ (1) x2-f ′ (2) x + 3, then the inclination angle of the tangent of F (x) at the point (0, f (0)) is () A. π4B. π3C. 2π3D. 34π

Analysis: from the meaning of the title: F ′ (x) = x2 + F ′ (1) x-f ′ (2), let x = 0, f ′ (0) = - F ′ (2), let x = 1, f ′ (1) = 1 + F ′ (1) - F ′ (2), f ′ (2) = 1, f ′ (0) = - 1, that is, the slope of the tangent of F (x) at point (0, f (0)) is - 1, and the inclination angle is 34 π
