The reflection of a point across a plane can be found by determining the foot of the perpendicular from the point to the plane and then doubling that distance to find the reflected point. The correct image point is (−3, 5, 2).

---|---|---|---|
A. | d²y/dx² + 13y = 0 | I. ex(c1 + c2x) | |
B. | d²y/dx² + 4dy/dx + 5y = cosh 5x | II. e2x(c1 cos 3x + c2 sin 3x) | |
C. | d²y/dx² + dy/dx + y = cos²x | III. c1ex + c2e3x | |
D. | d²y/dx² - 4dy/dx + 3y = sin 3x cos 2x | IV. e-2x(c1 cos x + c2 sin x) |
