What question?
lol it didnt post
G(f(2)) means work out whatever f(2) is then plug this into g(x).
So f(2) is 3 because we just find the x-value 2 in the left hand column and read across. This is 3.
So then we find g(3) by finding the x-value 3 in the left hand column and read across. This is 10.
So g(f(2)) = 10
1094
6562/6 = 1093.67 ~ 1094

Step-by-step explanation:
y varies directly with x.
The constant of variation is k = 7
Step-by-step explanation:
We have to check whether both vary directly with each other or not.
Every pair of x and y will be considered one by one
If y varies directly with x, it should satisfy y = kx or k = yx
So,
For x= -2, y=-14
![-14 = -2k\\k = \frac{-14}{-2}\\k = 7](https://tex.z-dn.net/?f=-14%20%3D%20-2k%5C%5Ck%20%3D%20%5Cfrac%7B-14%7D%7B-2%7D%5C%5Ck%20%3D%207)
For
x=3, y=21
![21 = 3k\\ k = \frac{21}{3}\\k = 7](https://tex.z-dn.net/?f=21%20%3D%203k%5C%5C%20k%20%3D%20%5Cfrac%7B21%7D%7B3%7D%5C%5Ck%20%3D%207)
For
x=5, y=35
![35 = 5k\\ k = \frac{35}{5}\\k = 7](https://tex.z-dn.net/?f=35%20%3D%205k%5C%5C%20k%20%3D%20%5Cfrac%7B35%7D%7B5%7D%5C%5Ck%20%3D%207)
As k is same for all pairs of x and y, it can be concluded that:
y varies directly with x.
The constant of variation is k = 7
