First Holiday Reflection

For my first blog for the holidays I’m going to review how to do chapter three section 5. how to find limits at infinity if it is a fraction then you follow the three rules:

1. if the degree of the top is equal to the degree of the bottom you divide the coefficients.
2. if the degree of the top is greater than the degree of the bottom you have to plug it into the table and find if it is positive or negative infinity.
3. if the top degree is less than the bottom degree it is equal to zero.

If it is not a fraction then you plug the equation into the y equals and use the table function. You plug in 10, 100, 1000, and 10,000.

Example:

Lim x-infinity 2x + 5 / 3x^2 + 1 = 0

Lim x-infinity 2x^2 + 5 / 3x^2 + 1 =2/3

Lim x-infinity 2x^3 +5 / 3x^2 + 1 = infinity
