+1.  If the tangent at the point $(x_1, y_1)$ on the curve $y = x^3 + 3x^2 + 5$ passes through the origin, then $(x_1, y_1)$ does NOT lie on the curve :

+2.  For the function $f(x) = 4\log_e(x - 1) - 2x^2 + 4x + 5$, $x > 1$, which one of the following is NOT correct?
+    *   A. f is increasing in $(1, 2)$ and decreasing in $(2, \infty)$
+    *   B. $f(x) = -1$ has exactly two solutions
+    *   C. $f'(e) - f''(2) < 0$
