Math Problem Statement

Find h'(3) if h(x) = f(g(x)) using the table of values provided.

Solution

We are asked to find h(3)h'(3), where h(x)=f(g(x))h(x) = f(g(x)), and we are provided a table with values for xx, f(x)f(x), f(x)f'(x), g(x)g(x), and g(x)g'(x).

Step-by-step approach:

  1. Since h(x)=f(g(x))h(x) = f(g(x)), we need to apply the chain rule to find h(x)h'(x): h(x)=f(g(x))g(x)h'(x) = f'(g(x)) \cdot g'(x)
  2. Now, to find h(3)h'(3), we need:
    • g(3)g(3)
    • f(g(3))f'(g(3))
    • g(3)g'(3)

From the table:

  • g(3)=2g(3) = 2 (looking at the row for g(x)g(x) where x=3x = 3).
  • f(2)=3f'(2) = 3 (looking at the row for f(x)f'(x) where x=2x = 2).
  • g(3)=4g'(3) = 4 (from the row for g(x)g'(x) where x=3x = 3).

Now, apply the chain rule: h(3)=f(g(3))g(3)=f(2)g(3)=34=12h'(3) = f'(g(3)) \cdot g'(3) = f'(2) \cdot g'(3) = 3 \cdot 4 = 12

Thus, h(3)=12h'(3) = 12.

Would you like more details or have any questions?

Here are 5 related questions to expand your understanding:

  1. What is the chain rule and how does it work in general?
  2. How would h(x)h'(x) change if h(x)=g(f(x))h(x) = g(f(x))?
  3. Can we interpret h(x)=f(g(x))h(x) = f(g(x)) as a composition of two functions, and how does this impact differentiation?
  4. What does the derivative g(x)g'(x) represent in this context?
  5. How would the result differ if f(x)f'(x) or g(x)g'(x) were negative?

Tip: Always double-check the table for the corresponding values, as small errors in reading values can affect the final result!
