Question #48732

Answer 1

Please see the explanation.

Explanation:

Given an equation of the form:

`y = ax^2+bx+c`

The domain of x is `-oo < x < oo`

Please notice that you cannot pick the abstract values of `-oo` or `+oo` for x.

However, you can pick an number that is "close" to either `-oo` or `+oo`.

Here is the problem with "close": Once you have made your choice of something "close" to `-oo` or `+oo`, I can pick a number that is closer by subtracting a number or adding a number respectively.

This has the effect of making y move closer and closer to `oo` but never reaching it. Therefore, there is no top or bottom two points.
