Math Problem Statement

We are to find f'(0) based on the derivative function f'(x) = e^x * g'(x) + g(x) * e^x, using given values g(0) = 4 and g'(0) = 2.

Solution

Let's go through the steps to find f(0)f'(0) based on the image provided:

  1. Given Function: f(x)=exg(x)+g(x)exf'(x) = e^x \cdot g'(x) + g(x) \cdot e^x

  2. At x=0x = 0: f(0)=e0g(0)+g(0)e0f'(0) = e^0 \cdot g'(0) + g(0) \cdot e^0

  3. Simplify e0e^0: Since e0=1e^0 = 1, this simplifies the equation to: f(0)=1g(0)+g(0)1f'(0) = 1 \cdot g'(0) + g(0) \cdot 1 f(0)=g(0)+g(0)f'(0) = g'(0) + g(0)

  4. Substitute Given Values: From the image, we are given: g(0)=4andg(0)=2g(0) = 4 \quad \text{and} \quad g'(0) = 2 Therefore: f(0)=2+4=6f'(0) = 2 + 4 = 6

Final Answer:

f(0)=6f'(0) = 6

Would you like further explanation on any part of this? Here are some related questions:

  1. What is the significance of exe^x in this function?
  2. How does the product rule apply in this derivative?
  3. Why does e0e^0 simplify to 1?
  4. What other methods could be used to evaluate f(0)f'(0)?
  5. How would this change if we were asked to find f(0)f''(0)?

Tip: Always remember that the derivative of exe^x with respect to xx is still exe^x, which is a powerful property in calculus!
