Math Problem Statement

Evaluate f(g(-5)) using the graphs of y = f(x) and y = g(x).

Solution

The problem asks to evaluate f(g(5))f(g(-5)) using the graphs of two functions: y=f(x)y = f(x) and y=g(x)y = g(x).

Step-by-Step Solution:

  1. Find g(5)g(-5):

    • To find g(5)g(-5), locate x=5x = -5 on the graph of g(x)g(x).
    • From the graph, at x=5x = -5, g(x)g(x) appears to be 22.
    • Thus, g(5)=2g(-5) = 2.
  2. Find f(g(5))=f(2)f(g(-5)) = f(2):

    • Now, use the value g(5)=2g(-5) = 2 and substitute it into f(x)f(x) to find f(2)f(2).
    • Locate x=2x = 2 on the graph of f(x)f(x).
    • From the graph, at x=2x = 2, f(x)=1f(x) = -1.
    • Thus, f(2)=1f(2) = -1.
  3. Conclusion:

    • The value of f(g(5))f(g(-5)) is f(2)=1f(2) = -1.

Final Answer:

f(g(5))=1f(g(-5)) = -1
