Infinite limits are what a certain equation is approaching. If you keep plugging in bigger numbers into the equation it will either go on forever or hit a dead end at a certain number.
*If you have a fraction with 2 polynomials divided use the these rules: (Refers to exponents)
1. Degree of top = degree of bottom leading coefficient/leading coefficient
2. Degree of top > degree of bottom + or - infinity (plug into equation to see if + or -)
3. Degree of top < degree of bottom 0
*If it does not follow the rules
1. Type the equation into y= in calculator
2. Hit 2nd table
3. Type in numbers 10, 100, 1000, 10000. Do more numbers if needed to see what number the equation is approaching.
*If it is geometric (has #^n)
1. If r <1 = 0
2. If r >1= + or - infinity
Examples: Find the limit of
A: (x+1)/x
The exponents are equal so 1/1= 1
The limit is 1
B: (.88) ^n
It’s geometric and r < 1 so the limit is 0
