Answer: B) 1/9, 3, 27
Step-by-step explanation:
Here, we need to evaluate
for 
So, we substitute values of x in the given function.
At x= -2, we have
![3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\ \ \ [\because\ a^{-n}=\dfrac{1}{a^n}]](https://tex.z-dn.net/?f=3%5E%7B-2%7D%3D%5Cdfrac%7B1%7D%7B3%5E2%7D%3D%5Cdfrac%7B1%7D%7B9%7D%5C%20%5C%20%5C%20%5B%5Cbecause%5C%20a%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5D)
At x= 1, we have

At x= 3

So, the values of
for
Thus, the correct answer is B) 1/9, 3, 27
Answer:
See below
Step-by-step explanation:
Tariku in second grade read 6 books each month during the year. This is equal to 6(12) = 72.
Tariku in third grade read 8 books each month during the year. This is equal to 8(12) = 96.
You can find the total amount with any of the below equations:
- 6(12) + 8(12)
- 12(6+8)
- 12(14)
For a total number of months x the equations would be the same except with x instead of 12.

10. Center (-1,-2) Radius 4
Ive attached what the graphs will look like, I cannot add the last graph since its the image limit for this website.
Hope this helps, feel free to PM me if you are still having trouble and need the last graph :)
Just so you know on your previous answer, you were wrong (not to sound rude) but -1/2 < 1.25
