No not all numbers are irrational and whole numbers are integers
These are 3 questions and 3 answers.1) Find
Answer: 4.Explanation:The expression means the
limit as the function f(x) approaches 2 from the right.Then, you have to use the function (the line) that comes from the right of 2 and gets as close as you want to x = 2.
That is the line that has the open circle around
y = 4, and that is the limit searched.
2) Use the graph to determine the limit if it exists.Answer: ![\lim_{x \to \ 2^-} f(x) = 3](https://tex.z-dn.net/?f=%20%5Clim_%7Bx%20%5Cto%20%5C%202%5E-%7D%20f%28x%29%20%3D%203)
![\lim_{x \to \ 2^+} f(x)=-3](https://tex.z-dn.net/?f=%20%5Clim_%7Bx%20%5Cto%20%5C%202%5E%2B%7D%20f%28x%29%3D-3%20)
To determine each limit you
use the function from the side the value of x is being approached.Note, that since the two limits are different it is said that the limit of the function as it approaches 2 does not exist.
3)
Answer: - 1![\lim_{x \to \ 3^-} f(x) = -1](https://tex.z-dn.net/?f=%20%5Clim_%7Bx%20%5Cto%20%5C%203%5E-%7D%20f%28x%29%20%3D%20-1%20)
To find the limit when the function is approached to 3 from the left you
follow the line that ends with the open circle at (3, -1).Therefore, the limit is - 1.
Answer:
B
Step-by-step explanation:
It's B because two negatives equal a positive.
C. The absolute value of -45 is 45, leaving the extra negative to hang on in there ---> -|-45|= 45= (bring the negative back over) -45
D. Self explanatory its -45 alone lol.

x= -7
