Question:

Which of the following functions is a solution to the differential equation as y''+y' -2y =0

Options:

\[y = { e }^{ -2x } \]

\[y = { e }^{ 2x } \]

\[y = { e }^{ x } \]

\[y = { e }^{ -4x } \]

Correct Answer:

\[y = { e }^{ -2x } \]

Explanation:

\(y = { e }^{ -2x } \)

\(y'' = 4 { e }^{ -2x } \)
