Solve as a simultaneous equation maybe?
f(x) + g(x) = 2x or x/(x-6) + y =2x
and then solve so it becomes 2x^2 + 5x =y
then factorise into brackets or use quadratic formula
Take a look at the image below.
Answer:
I would say its the bottom one
Step-by-step explanation:
The top one goes to five while the bottom only goes to four, plus you cant have a negative amount of people you can only have from 0 to infinity amount of people.
I dont think the answer is always. Because integers are always whole numbers. Hope that helps a little?
Answer:

Step-by-step explanation:
We are given that a function

We have to find the average value of function on the given interval [0,7]
Average value of function on interval [a,b] is given by

Using the formula

![f_{avg}=\frac{1}{7}[e^{\frac{x}{7}}\times 7)]^{7}_{0}](https://tex.z-dn.net/?f=f_%7Bavg%7D%3D%5Cfrac%7B1%7D%7B7%7D%5Be%5E%7B%5Cfrac%7Bx%7D%7B7%7D%7D%5Ctimes%207%29%5D%5E%7B7%7D_%7B0%7D)
By using the formula


Because 

Hence, the average value of function on interval [0,7]
