To complete the table for the function $f(x) = x - 1$, we need to substitute each value of $x$ into the function and find the corresponding $f(x)$.

Given:

$f(x) = x - 1$

Let's calculate:

1. For $x = 2$: $f(2) = 2 - 1 = 1$

2. For $x = 4$: $f(4) = 4 - 1 = 3$

3. For $x = 6$: $f(6) = 6 - 1 = 5$

4. For $x = 8$: $f(8) = 8 - 1 = 7$

Now, the completed table is:

\hline x & f(x) \\ \hline 2 & 1 \\ \hline 4 & 3 \\ \hline 6 & 5 \\ \hline 8 & 7 \\ \hline \end{array}$$ Would you like more details on how these calculations were done or have any questions? Here are five related questions to deepen your understanding: 1. What would the table look like for $$f(x) = 2x - 1$$? 2. How would the table change if $$f(x) = x + 2$$? 3. Can you find $$f(x)$$ if $$x = 10$$ using the same function? 4. What is the inverse function of $$f(x) = x - 1$$? 5. How would the graph of $$f(x) = x - 1$$ look? **Tip:** When working with functions, always ensure you're substituting the correct value of $$x$$ into the function to find $$f(x)$$.
