Final Review #3 HW

Given h(x) =f (x) g(x) , find h'(2)

• 1/3

• 10/3

• 4/3

• 7/3

Given h(x) = f (g(x)), find h'(3)

• 9/2

• 3/2

• -3/2

• 1/2

Find the derivative f(x) = xe^x

• f'(x) = e^x

• f'(x) = xe^x + xe^x

• f'(x) = e^x - xe^x

• f'(x) = e^x + xe^x

Find the derivative
f(t) = (t² + 2t)⁵

• f'(t) = 5(2t+2)⁴
• f'(t) = 5(t² + 2t)⁴
•  f'(t) = 5(t² + 2t)⁴(2t)
• f'(t) = 5(t² + 2t)⁴(2t + 2)

Find the second derivative of
f(x) = x² + e^x  - cosx

• f"(x) = 2 + e^x + cosx
• f"(x) = 2x + e^x + cosx
• f"(x) = 2x + xe^x - cosx
• f"(x) = 2x + e^x + sinx

Find y' if y=e^3x

• e^3x
• e^2x
• 0
• 3e^3x
