Solution

To complete the table for the function f(x)=2x4f(x) = -2x - 4, let's calculate f(x)f(x) for each given value of xx.

f(x)=2x4f(x) = -2x - 4

  1. For x=0x = 0: f(0)=2(0)4=04=4f(0) = -2(0) - 4 = 0 - 4 = -4

  2. For x=1x = 1: f(1)=2(1)4=24=6f(1) = -2(1) - 4 = -2 - 4 = -6

  3. For x=2x = 2: f(2)=2(2)4=44=8f(2) = -2(2) - 4 = -4 - 4 = -8

  4. For x=3x = 3: f(3)=2(3)4=64=10f(3) = -2(3) - 4 = -6 - 4 = -10

The completed table is:

\hline x & f(x) \\ \hline 0 & -4 \\ 1 & -6 \\ 2 & -8 \\ 3 & -10 \\ \hline \end{array}$$ Would you like a detailed explanation of how each value was calculated or have any other questions? --- Here are five related questions for further practice: 1. What would be the value of $$f(x)$$ if $$x = -1$$? 2. How does the function $$f(x) = -2x - 4$$ behave as $$x$$ increases? 3. Determine the x-intercept of the function $$f(x) = -2x - 4$$. 4. What is the slope of the function $$f(x) = -2x - 4$$? 5. How does the graph of $$f(x) = -2x - 4$$ compare to the graph of $$f(x) = -2x + 4$$? **Tip:** When working with linear functions, the coefficient of $$x$$ represents the slope, which tells you how steep the line is.
