Given that the soup recipe uses 6 cups of water, 4 cups of tomato sauce, and 5 cups of tomato puree, to get the number of cups of tomato sauce required for every cup of water, we would reduce the ratio of the cups of tomato sauce and cups of water required in a manner that the cups of water is 1.
The ratio of the cups of tomato sauce to the cups of water
= 4:6
Dividing both by 6 the ratio becomes
= 2/3 : 1
Hence for each cup of water, there must be 2/3 cup of tomato sauce
Method: First you must substitute g(x) into f(x). Where the x is in the equation f(x) substitute the equation of g(x). So it should be fg(x) = (x4)²+ 8(x4). Then simplify the equation to fg(x) = 16x² + 32x
