Answer:
setup below, you'll have to do the final calculation
Step-by-step explanation:
first perform the operation in parenthesis
2+39= 41
then do the multiplication 3 x 41
in general do calculations in this order
1. Parenthesis
2. Multiplication
3. Division
4. Addition
5. Subtraction
working from left to right
So to multiply standard form we multiply the 2 numbers and the 2 indices separately.
![2.6*3.9=10.14](https://tex.z-dn.net/?f=2.6%2A3.9%3D10.14)
![x^{2} * x^{11} = x^{13}](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2A%20%20x%5E%7B11%7D%20%3D%20x%5E%7B13%7D%20)
So we've got
![10.14*10^{13}](https://tex.z-dn.net/?f=10.14%2A10%5E%7B13%7D)
However Standard form must be
![1 \leq x \leq 10](https://tex.z-dn.net/?f=1%20%5Cleq%20x%20%5Cleq%2010)
therefore we need to divide that by 10 but to get the same number we add one onto the power of 10.
So the answer is:
lbs of oxygen are produced in the rainforest each year.
Plug in the f(x+1)
f(x+1) = (x+1)^2
I would say number 1. looks the most correct
CHECK BY THESE POINTS
(-1, -3)
(-2, 0)
(-1, 1)
(0, 8)
Hope this helps :)
