Math Problem Statement

Let f(x) = e^{g(x)}, where g(0) = 6 and g'(0) = 2. Find f'(0).

Solution

Let's start by solving problem 11, which states:

Problem 11: Let f(x)=eg(x)f(x) = e^{g(x)}, where g(0)=6g(0) = 6 and g(0)=2g'(0) = 2. Find f(0)f'(0).

Solution:

To find f(x)f'(x), we need to differentiate f(x)=eg(x)f(x) = e^{g(x)} using the chain rule.

  1. The derivative of f(x)=eg(x)f(x) = e^{g(x)} is: f(x)=eg(x)g(x)f'(x) = e^{g(x)} \cdot g'(x)
  2. Now, substitute x=0x = 0: f(0)=eg(0)g(0)f'(0) = e^{g(0)} \cdot g'(0)
  3. We're given that g(0)=6g(0) = 6 and g(0)=2g'(0) = 2, so: f(0)=e62f'(0) = e^6 \cdot 2 f(0)=2e6f'(0) = 2e^6

Thus, the value of f(0)f'(0) is 2e62e^6.

Here are five related questions for further practice:

  1. If h(x)=ln(g(x))h(x) = \ln(g(x)) and g(0)=6g(0) = 6, g(0)=2g'(0) = 2, find h(0)h'(0).
  2. Differentiate f(x)=e3g(x)f(x) = e^{3g(x)} with respect to xx.
  3. Find the second derivative f(0)f''(0) for the same function f(x)=eg(x)f(x) = e^{g(x)}.
  4. Solve f(x)f'(x) if f(x)=eg(x)+x2g(x)f(x) = e^{g(x)} + x^2g(x).
  5. If g(x)=sin(x)g'(x) = \sin(x), find f(x)f'(x) for f(x)=eg(x)f(x) = e^{g(x)}.

Tip: Always apply the chain rule when differentiating composite functions like eg(x)e^{g(x)}.
