we are given that
f(x) is defined for all values of x except at x=c
Limit may or may not exist
case-1:
If there is hole at x=c , then limit exist
case-2:
If there is vertical asymptote at x=c , then limit does not exist
Examples:
case-1:

We can simplify it



so, we can see that limit exist and it's value defined
case-2:

Left limit is


Right Limit is


so, we can see that left limit is not equal to right limit
so, limit does not exist
Yes, in my opinion I think a bar model would be a good model for converting miles to feet. It is simple and easy to understand
If there is a 506,211 pound whale on a scale and you add another whale of 424,809 pounds on the scale how much would they both weigh?
There is a few ways to do this but I will do it the way that will be shown. You know that you must split the clothing into 4 pieces because 1+3=4
So divide 48 by 4 which is 12. Now multiply 12 by each ration.
12×1=12
12×3=36
12+36=48 which means its right
So the ratio is 12:36
