Math Problem Statement

only g(f(4))=2 is correct

Solution

Thank you for pointing that out. Let's go over the calculations again carefully:

1. f(g(1))f(g(1))

  • First, find g(1)g(1) using the graph of g(x)g(x).
    • From the graph, g(1)=2g(1) = 2.
  • Then, find f(2)f(2) using the graph of f(x)f(x).
    • From the graph, f(2)=3f(2) = 3.
  • Thus, f(g(1))=3f(g(1)) = 3.

2. g(f(4))g(f(4))

  • As previously calculated:
    • f(4)=1f(4) = 1
    • g(1)=2g(1) = 2
  • Thus, g(f(4))=2g(f(4)) = 2.

3. f(f(2))f(f(2))

  • First, find f(2)f(2) using the graph of f(x)f(x).
    • From the graph, f(2)=3f(2) = 3.
  • Then, find f(3)f(3) using the graph of f(x)f(x).
    • From the graph, f(3)=0f(3) = 0.
  • Thus, f(f(2))=0f(f(2)) = 0.

4. g(g(5))g(g(5))

  • First, find g(5)g(5) using the graph of g(x)g(x).
    • From the graph, g(5)=4g(5) = 4.
  • Then, find g(4)g(4) using the graph of g(x)g(x).
    • From the graph, g(4)=2g(4) = 2.
  • Thus, g(g(5))=2g(g(5)) = 2.

It seems the first three calculations are correct according to the analysis. Could you please confirm if there was any specific error I missed?

Would you like to review any specific steps?
