Math Problem Statement

Complete the table below given that g(x) = f(-x). The table provides values for x and f(x), and the user is asked to fill in the corresponding values for g(x).

Solution

The problem asks to complete the table given that g(x)=f(x)g(x) = f(-x).

We already have the values of xx and f(x)f(x), and we are asked to fill in the table for g(x)g(x). The key here is that g(x)=f(x)g(x) = f(-x), which means that the value of g(x)g(x) at some xx is the same as f(x)f(x) at the corresponding negative xx.

Steps to Solve:

  1. For each value of xx in the bottom table, find the corresponding value of x-x and use the known value of f(x)f(-x) from the top table to fill in g(x)g(x).

Let's go through each step:

For x=8x = 8:

  • We need g(8)=f(8)g(8) = f(-8).
  • From the table, f(8)=9f(-8) = -9.
  • So, g(8)=9g(8) = -9.

For x=10x = 10:

  • We need g(10)=f(10)g(10) = f(-10).
  • From the table, f(10)=8f(-10) = -8.
  • So, g(10)=8g(10) = -8.

For x=11x = -11:

  • We need g(11)=f(11)g(-11) = f(11).
  • From the table, f(11)=6f(11) = -6.
  • So, g(11)=6g(-11) = -6.

For x=15x = -15:

  • We need g(15)=f(15)g(-15) = f(15).
  • From the table, f(15)=4f(15) = -4.
  • So, g(15)=4g(-15) = -4.

Final Table:

xx810-11-15
g(x)g(x)-9-8-6-4

Here are 5 follow-up questions that expand on this topic:

  1. What is the relationship between even and odd functions with respect to f(x)f(-x)?
  2. How would the table change if g(x)=f(x)g(x) = -f(-x)?
  3. How can you graphically represent the transformation g(x)=f(x)g(x) = f(-x)?
  4. If f(x)f(x) is a linear function, how does g(x)=f(x)g(x) = f(-x) affect its slope and intercepts?
  5. How would you approach the problem if given a quadratic function instead of f(x)f(x)?

Tip: When dealing with function transformations like f(x)f(-x), you are performing a reflection of the graph across the y-axis.
