Match the solutions to the differential equations. If there is more than one solution to an equation, select the answer that includes all solutions.

 1. $\frac{d^2y}{dx^2}=64 y$
 2. $\frac{dy}{dx}=-8 y$
 3. $\frac{dy}{dx}=8 y$
 4. $\frac{d^2y}{dx^2}=-64 y$

A. $y = \sin(8 x)$ or $y = 8\sin(x)$
B. $y = e^{8 x}$
C. $y = 8\sin(x)$
D. $y = \sin(8 x)$
E. $y = e^{-8 x}$ or $y = e^{8 x}$
F. $y = e^{-8 x}$
