Domain, Range, Monotonocity.

Consequently, the graph will be able to be roughly sketched and will look like this: graph{-2/x [-10, 10, -5, 5]}.

To graph the function ( y = -\frac{2}{x} ), identify the key elements:

- The function is a rational function.
- The numerator is a constant (-2).
- The denominator is a variable (x).
- Determine the behavior as x approaches positive and negative infinity.
- Look for vertical and horizontal asymptotes.
- Plot points to understand the shape of the graph.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
