Math Problem Statement

Which statement is true regarding the graphed functions?

Solution

Looking at the graph, we have two functions: f(x)f(x) (in blue) and g(x)g(x) (in red). Let's analyze the given points from the graph to check which statement is true.

Step 1: Find the value of f(0)f(0) and g(2)g(-2)

  • From the graph, at x=0x = 0:

    • f(0)=4f(0) = 4 (the blue curve is at 4 when x=0x = 0)
    • g(0)=0g(0) = 0 (the red curve crosses the x-axis at 0)
  • Now for g(2)g(-2):

    • g(2)=4g(-2) = 4 (the red curve reaches a value of 4 when x=2x = -2)

Step 2: Check each option

  • Option 1: f(0)=2f(0) = 2 and g(2)=0g(-2) = 0

    • Incorrect. f(0)=4f(0) = 4, not 2.
  • Option 2: f(0)=4f(0) = 4 and g(2)=4g(-2) = 4

    • Correct! This matches the values from the graph.
  • Option 3: f(2)=0f(-2) = 0 and g(2)=0g(-2) = 0

    • Incorrect. g(2)=4g(-2) = 4, not 0.
  • Option 4: f(4)=4f(4) = 4 and g(4)=4g(-4) = 4

    • Incorrect. f(4)f(4) does not exist on the graph and g(4)g(-4) is not 4.

Conclusion:

The correct statement is Option 2: f(0)=4f(0) = 4 and g(2)=4g(-2) = 4.

Relative Questions:

  1. How do you find the values of functions from a graph?
  2. Can you explain why g(x)=0g(x) = 0 at certain points?
  3. What does it mean for a function to cross the x-axis?
  4. How do quadratic functions typically behave based on their graphs?
  5. Can you derive the equations for f(x)f(x) and g(x)g(x) from this graph?

Tip:

Always check the behavior of both functions at key points like x=0x = 0 and the intercepts for better understanding.
