Math Problem Statement

på dansk

En funktion f er givet ved f(x) = 2e^{4x+2}. Bestem f'(x).

Solution

For the given function:

f(x)=2e4x+2f(x) = 2e^{4x+2}

We are tasked to find the derivative f(x)f'(x).

Solution:

The function involves an exponential term, so we apply the chain rule. The derivative of eue^{u} is euue^u \cdot u', where u=4x+2u = 4x+2.

  1. Rewrite the function: f(x)=2e4x+2f(x) = 2e^{4x+2}

  2. Compute the derivative of 4x+24x+2: u=4x+2u=4u = 4x + 2 \quad \Rightarrow \quad u' = 4

  3. Apply the chain rule: f(x)=2e4x+24f'(x) = 2 \cdot e^{4x+2} \cdot 4

  4. Simplify the expression: f(x)=8e4x+2f'(x) = 8e^{4x+2}

Final Answer:

f(x)=8e4x+2f'(x) = 8e^{4x+2}

Let me know if you need further details or explanations! Here are related questions to explore:

  1. How do you differentiate exponential functions with more complex exponents?
  2. How does the chain rule apply to functions of multiple variables?
  3. Can you integrate f(x)=2e4x+2f(x) = 2e^{4x+2}?
  4. What is the behavior of f(x)f'(x) as xx \to \infty?
  5. How does the derivative f(x)f'(x) relate to the slope of f(x)f(x)?

Tip: Always simplify exponents before differentiation to make the process more straightforward.
