Answer:
The limit of the function as x approaches to -1, is -1 and the option 4 is correct.
Step-by-step explanation:
According the the definition of limit, if,

Then the limit of function exist. Either the function is defined or not on the point a. If the at point a the value value of function is L, then the function is continuous.
From the given graph it is easily noticed that the value of f(x) approaches to -1 as x approaches to -1 from left or left. At x=-1 there is a open circle on (-1,-1), therefore this is not included in the function.
The value of f(x) is 2 at x=-1 because of the point (-1,-2).

Therefore the limit of the function exist and the limit of the function is -1.
The problem asked you to calculate the slope of the dilated polygon which is dilated by a scale factor of 3. So, the slope of BC is 5/2 or -5/-2 and the dilated polygon has a the same slope of the original polygon.
Hope this helps :)
Answer:
okay so.
Step-by-step explanation:
1. they're the same.
2. theyre also the same. simplify them both and u get 3/4.
3. not the same.
4. not the same. can't be simplified.
5. not sure someone else can try
Hope this help to answer you question.
