1. Visualization and interpretation of the limit

2. The values of f decrease without bound
The values of f decrease without bound. In absolute terms they increase without bound.
The values of x approach a from the right. i.e. the values of x decrease to a
We present in the next slide the graph of a function with this limit.

3. f (x) decreases without bound as

4. This limit indicates that the line x = a is a vertical asymptote in the negative direction

5. An interpretation of this limit
If i is the income of a household and D is its deficit, the limit
Is interpreted as

6. the deficit D decreases without bound
the deficit D decreases without bound. In absolute terms it increases without bound.
as the income i decreases to a
As the income decreases to a, the debt, in absolute terms, increases and reaches a level of insolvency.
