It is not 7 it is 12. 3x4 = 12
The graph of f(x) = sqrt( 4x) looks like this. So choose the one that looks like the image attached.

Step-by-step explanation: 3182400060 tens and 100 hundreds = 31824010600.
1 grain = 103g
2kg = 2000g
grains = 2000g/103g = 19.417
Answer:
About 19.417 grains
4. Since f(x) = 2x - 1, we are looking for h(2x - 1), which is (2x-1)^2 + 1. By tha time you expand this you'll get, 4x^2 - 4x + 2. So that is the answer.
5. f(f(x)) = f(2x - 1) = 2(2x - 1) - 1 = 4x - 3
6. h(g(x)) = h(3x) = (3x)^2 + 1 = 9x^2 + 1
