Math Problem Statement

Use the graphs to evaluate the expressions.

Solution

Let's evaluate the expressions one by one using the given graphs for f(x)f(x) and g(x)g(x).

1. f(g(2))f(g(2)):

  • First, find g(2)g(2) from the graph of g(x)g(x). From the graph, g(2)=1g(2) = 1.
  • Next, substitute g(2)=1g(2) = 1 into f(x)f(x). From the graph of f(x)f(x), f(1)=5f(1) = 5.
  • Therefore, f(g(2))=5f(g(2)) = 5.

2. g(f(0))g(f(0)):

  • First, find f(0)f(0) from the graph of f(x)f(x). From the graph, f(0)=3f(0) = 3.
  • Next, substitute f(0)=3f(0) = 3 into g(x)g(x). From the graph of g(x)g(x), g(3)=2g(3) = 2.
  • Therefore, g(f(0))=2g(f(0)) = 2.

3. f(f(1))f(f(1)):

  • First, find f(1)f(1) from the graph of f(x)f(x). From the graph, f(1)=5f(1) = 5.
  • Next, substitute f(1)=5f(1) = 5 into f(x)f(x). From the graph of f(x)f(x), f(5)=0f(5) = 0.
  • Therefore, f(f(1))=0f(f(1)) = 0.

4. g(g(3))g(g(3)):

  • First, find g(3)g(3) from the graph of g(x)g(x). From the graph, g(3)=2g(3) = 2.
  • Next, substitute g(3)=2g(3) = 2 into g(x)g(x). From the graph of g(x)g(x), g(2)=1g(2) = 1.
  • Therefore, g(g(3))=1g(g(3)) = 1.

Final answers:

  • f(g(2))=5f(g(2)) = 5
  • g(f(0))=2g(f(0)) = 2
  • f(f(1))=0f(f(1)) = 0
  • g(g(3))=1g(g(3)) = 1

Let me know if you need further explanation or details! Here are 5 related questions for practice:

  1. What is g(f(2))g(f(2))?
  2. What is f(f(2))f(f(2))?
  3. What is g(g(0))g(g(0))?
  4. What is f(g(0))f(g(0))?
  5. What is f(g(1))f(g(1))?

Tip: For composite functions, always work from the innermost function outward.
