We write the function f like this:
![f(x)=72(1+0.25)^x](https://tex.z-dn.net/?f=f%28x%29%3D72%281%2B0.25%29%5Ex)
It means that the price is increasing by
![25\%](https://tex.z-dn.net/?f=25%5C%25)
a year.
B)Let compute the price change of the product B:
![\frac{142.81-109.85}{109.85}\times100=30\%](https://tex.z-dn.net/?f=%20%5Cfrac%7B142.81-109.85%7D%7B109.85%7D%5Ctimes100%3D30%5C%25%20)
We deduce that product B recorded a greater percentage.
The correct statement that would best describe the graph would be option A. Simply make a table of values to see how It will turn out.
For instance plugging in x = 1, y = 1 for the f(x) graph.
For g(x) = it would be 1,1/9.
There had been a compression.
Answer:
30
Step-by-step explanation:
x = 2, y = 7 and z = 6
so 4(x + y) —z = 4(2+7) - 6
= 4(9) - 6
= 36 -6
= 30
What you do is first add all of the numbers then you round to the nearest 10th
