Math Problem Statement

Evaluate: g(f(-5))

Solution

To evaluate g(f(5))g(f(-5)), we need to follow these steps:

  1. Find f(5)f(-5) from the y=f(x)y = f(x) graph.

    • At x=5x = -5, the graph shows that f(5)=8f(-5) = -8.
  2. Use the result from step 1 to find g(8)g(-8) from the y=g(x)y = g(x) graph.

    • At x=8x = -8, the y=g(x)y = g(x) graph shows that g(8)=4g(-8) = 4.

Thus, g(f(5))=4g(f(-5)) = 4.

Here are some related questions for further exploration:

  1. How do you evaluate f(g(3))f(g(-3)) using the graphs?
  2. What happens to the composition g(f(x))g(f(x)) when x=0x = 0?
  3. How do you determine the range of g(f(x))g(f(x)) over the interval 10x10-10 \leq x \leq 10?
  4. How do you find g(f(2))g(f(2)) using the graphs?
  5. What is the inverse of the function ff or gg, if they exist?

Tip: When evaluating composite functions like g(f(x))g(f(x)), always start with the inner function.
