To compute the values of the function \( f(x) = \frac{1}{x - 2} \) for the given x-values, we will evaluate the function for each \( x \).

  1. For \( x = -2 \):
    \( f(-2) = \frac{1}{-2 - 2} = \frac{1}{-4} = -\frac{1}{4} \)

  2. For \( x = -1 \):
    \( f(-1) = \frac{1}{-1 - 2} = \frac{1}{-3} = -\frac{1}{3} \)

  3. For \( x = 0 \):
    \( f(0) = \frac{1}{0 - 2} = \frac{1}{-2} = -\frac{1}{2} \)

  4. For \( x = 1 \):
    \( f(1) = \frac{1}{1 - 2} = \frac{1}{-1} = -1 \)

  5. For \( x = 2 \):
    \( f(2) = \frac{1}{2 - 2} \) is undefined. So, we will write N (not defined).

  6. For \( x = 3 \):
    \( f(3) = \frac{1}{3 - 2} = \frac{1}{1} = 1 \)

  7. For \( x = 4 \):
    \( f(4) = \frac{1}{4 - 2} = \frac{1}{2} \)

Now we can summarize the table of values:

| \( x \) | \( f(x) \) | |---------|-------------------------| | -2 | -\(\frac{1}{4}\) | | -1 | -\(\frac{1}{3}\) | | 0 | -\(\frac{1}{2}\) | | 1 | -1 | | 2 | N | | 3 | 1 | | 4 | \(\frac{1}{2}\) |

Summary of Results:

  • \( f(-2) = -\frac{1}{4} \)
  • \( f(-1) = -\frac{1}{3} \)
  • \( f(0) = -\frac{1}{2} \)
  • \( f(1) = -1 \)
  • \( f(2) = N \) (undefined)
  • \( f(3) = 1 \)
  • \( f(4) = \frac{1}{2} \)

Graphing the Points:

On a coordinate system, you can plot the points:

  • (-2, -1/4)
  • (-1, -1/3)
  • (0, -1/2)
  • (1, -1)
  • (3, 1)
  • (4, 1/2)

Note on the function:

The function has a vertical asymptote at \( x = 2 \), which means that the function approaches infinity or negative infinity as \( x \) approaches 2 from the left or right. Thus, in a graph, there will be a break at that point.

You can sketch the graph based on these points and the characteristics of the function!
