Answer:
(g•f)(x) = x.
Step-by-step explanation:
Let 
, then the inverse function of the f(x) is 
So, (g•f)(x) = ![g[f(x)] = g(x^{2} + 1 ) = \sqrt{(x^{2} + 1) - 1} = \sqrt{x^{2} } = x](https://tex.z-dn.net/?f=g%5Bf%28x%29%5D%20%3D%20g%28x%5E%7B2%7D%20%2B%201%20%29%20%3D%20%5Csqrt%7B%28x%5E%7B2%7D%20%2B%201%29%20-%201%7D%20%3D%20%5Csqrt%7Bx%5E%7B2%7D%20%7D%20%3D%20x)
Therefore, we can write if f(x) and g(x) are inverse functions of each other, then (g•f)(x) = x.
Hence, option D is correct. (Answer)

Answer:
Yes, she will have enough eggs.
Step-by-step explanation:
It's an easy question if we carefully think about it.
Firstly we find the total number of eggs:
- 9 boxes x 15 eggs = 135 eggs
Secondly, the weight of the useful egg whites:
- 135 eggs x 40 grams = 5400 grams of egg whites
Thirdly we divide the egg whites weight by the sugar weight
- 5400/8000 = 0.675 which is larger than the minimum ratio, 3/5 = 0.6.
This means that Keely will have enough eggs to use the whole of the sugar for meringues.
Answer:
P'(-6,-4)
Step-by-step explanation:
By translating the point under the translation, to put it into a simpler form, it says to move the point 4 units to the left and 6 units down. Using this, the point will move to P'(-6,-4)
