The graph is

Step by step solution

Step 1. Given information.

The given function is,

$f (x) = \frac{1}{x}$ .

Step 2. Finding the symmetry.

Now substituting $x = - x$ in the given function then,

$f (- x) = \frac{1}{- x} = - \frac{1}{x} = - f (x)$

Therefore, the function is an odd function and symmetric with respect to the origin.

Step 3. Finding the ordered pairs.

Using the point plotting method we get,

$x$	$y = f (x) = \frac{1}{x}$	$(x, y)$
$- 1$	$y = \frac{1}{- 1} = - 1$	$(- 1, - 1)$
$1$	$y = \frac{1}{1} = 1$	$(1, 1)$
$2$	$y = \frac{1}{2}$	$(2, \frac{1}{2})$

Step 4. Plotting the points on a graph.

The graph is
