Math Problem Statement

Use the tables to evaluate the given composite function (g ∘ f)(-5).

Solution

To solve (gf)(5)(g \circ f)(-5), we need to evaluate the composite function step-by-step:

Step 1: Find f(5)f(-5)

Using the first table, we locate x=5x = -5. The corresponding value for f(x)f(x) is: f(5)=3f(-5) = 3

Step 2: Find g(f(5))=g(3)g(f(-5)) = g(3)

Now that f(5)=3f(-5) = 3, we use the second table to find g(3)g(3). When x=3x = 3, the value of g(x)g(x) is: g(3)=3g(3) = -3

Final Answer:

Thus, (gf)(5)=g(f(5))=g(3)=3(g \circ f)(-5) = g(f(-5)) = g(3) = -3.

(gf)(5)=3(g \circ f)(-5) = -3

Here are 5 related questions to explore:

  1. How do you evaluate (fg)(1)(f \circ g)(-1) using the given tables?
  2. What is g(f(2))g(f(2)) using the same tables?
  3. Can you find f(f(5))f(f(-5)) by applying ff twice?
  4. How do composite functions work if the range of ff doesn't match the domain of gg?
  5. What are the domain and range of ff and gg based on the tables?

Tip: When working with composite functions, always evaluate the inner function first and then use its result as the input for the outer function.
