question 7

Multiple Choice

Find the first and second derivatives of f(x) = $$\frac { 1 - 2 x } { e ^ { x } }$$ .

• A) f'(x) = 2x \(e ^ { x }\) - 3 \(e ^ { x }\), F''(x) = 2x \(e ^ { x }\) - \(e ^ { x }\)
• B) f'(x) = 4x \(e ^ { x }\) - 2 \(e ^ { x }\), F''(x) = 4x \(e ^ { x }\) + 2 \(e ^ { x }\)
• C) f'(x) = \(\frac { 3 - 2 x } { e ^ { x } }\), F''(x) = \(\frac { 2 x - 5 } { e ^ { x } }\)
• D) f'(x) = \(\frac { 2 x - 3 } { e ^ { x } }\), F''(x) = \(\frac { 5 - 2 x } { e ^ { x } }\)
