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,
![L=\lim_{x\rightarrow a^+}f(x)=\lim_{x\rightarrow a^-}f(x)](https://tex.z-dn.net/?f=L%3D%5Clim_%7Bx%5Crightarrow%20a%5E%2B%7Df%28x%29%3D%5Clim_%7Bx%5Crightarrow%20a%5E-%7Df%28x%29)
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).
![\lim_{x\rightarrow -1^+}f(x)=\lim_{x\rightarrow -1^-}f(x)=-1](https://tex.z-dn.net/?f=%5Clim_%7Bx%5Crightarrow%20-1%5E%2B%7Df%28x%29%3D%5Clim_%7Bx%5Crightarrow%20-1%5E-%7Df%28x%29%3D-1)
Therefore the limit of the function exist and the limit of the function is -1.
20%
This is because 20 and it's opposite -20 is 40. (20 - -20 = 40). Then 40 is 20% of 200.
It should take 20.88 years to grow $10000 by $25000 if compounded continuously.
Answer:
<em>-5/4</em>
Step-by-step explanation:
7(x + 4) + 1x - 9 * 2 = -8x + -10
Distribute 7 on left side. Multiply 9 * 2 on left side.
7x + 28 + 1x - 18 = -8x + -10
Combine like terms on left side.
8x + 10 = -8x + -10
Add 8x to both sides. Subtract 10 from both sides.
16x = -20
Divide both sides by 16.
x = -20/16
Reduce the fraction.
x = -5/4
