Answer:
D.
Step-by-step explanation:
A multiple is a number that can be divided by another number without a remainder. These are all multiples of 12 because they can all be divided by another number without a remainder.
I believe you're asking about the one-sided limit,
![\displaystyle \lim_{x\to-4^-}\frac{|x+4|}{x+4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clim_%7Bx%5Cto-4%5E-%7D%5Cfrac%7B%7Cx%2B4%7C%7D%7Bx%2B4%7D)
Recall the definition of absolute value:
•
if ![x\ge0](https://tex.z-dn.net/?f=x%5Cge0)
•
if ![x < 0](https://tex.z-dn.net/?f=x%20%3C%200)
Since we're approaching -4 from the left, we're effectively focusing on a domain of
or
. So, by the definition above, we have
. Then in the limit, we have
![\displaystyle \lim_{x\to-4^-}\frac{|x+4|}{x+4} = \lim_{x\to-4^-}\frac{-(x+4)}{x+4} = \lim_{x\to-4^-}(-1) = \boxed{-1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clim_%7Bx%5Cto-4%5E-%7D%5Cfrac%7B%7Cx%2B4%7C%7D%7Bx%2B4%7D%20%3D%20%5Clim_%7Bx%5Cto-4%5E-%7D%5Cfrac%7B-%28x%2B4%29%7D%7Bx%2B4%7D%20%3D%20%5Clim_%7Bx%5Cto-4%5E-%7D%28-1%29%20%3D%20%5Cboxed%7B-1%7D)
Answer:
Step-by-step explanation:
(4.5 · 10^7)(5.8 · 10^1)
(4.5 · 10,000,000)(5.8 · 10)
(45,000,000)(58)
2,610,000,000
2.61 · 10^9
The X-intercepts are where the blue line cross the X-axis.
There is a black dot at (-3,0) and (1,0)
The answer would be the 2nd choice.
