Open or closed? because if it's closed then the the answer is D
All that is needed is that it is 270
Step-by-step explanation:
we have to change symbol when dividing by negative number
y < 161 / 7
but in second
y > -161/7
It went up a total of $5.66 cents in an average of 20 years
Answer:
will be the solutions.
Step-by-step explanation:
The given equation is ![y=C_{1}e^{x}+C_{2}e^{-x}](https://tex.z-dn.net/?f=y%3DC_%7B1%7De%5E%7Bx%7D%2BC_%7B2%7De%5E%7B-x%7D)
Therefore, for x = -1
------(1)
Now y'(-1) = -4
y'(x) =
= -4
= -4 -----(2)
By adding equation (1) and (2)
![2C_{1}e^{-1}=0](https://tex.z-dn.net/?f=2C_%7B1%7De%5E%7B-1%7D%3D0)
![C_{1}=0](https://tex.z-dn.net/?f=C_%7B1%7D%3D0)
From equation (1),
![4=0+C_{2}e^{1}](https://tex.z-dn.net/?f=4%3D0%2BC_%7B2%7De%5E%7B1%7D)
![C_{2}=4e^{-1}](https://tex.z-dn.net/?f=C_%7B2%7D%3D4e%5E%7B-1%7D)
By placing the values in the parent equation
y = ![4e^{-1}\times e^{-x}](https://tex.z-dn.net/?f=4e%5E%7B-1%7D%5Ctimes%20e%5E%7B-x%7D)
y = ![4e^{-(x+1)}](https://tex.z-dn.net/?f=4e%5E%7B-%28x%2B1%29%7D)
