x â 1. and then multiply by â2: â2(x â 1) = â2 x + 2. b) Prove that f (x) and g (x) are inverses. f (g (x)) = âÂ½(â2 x + 2) + 1 = x â 1 + 1 = x. and. g (f (x)) = â2(âÂ½ x + 1) + 2 = x â 2 + 2 = x. One sometimes sees that to find the inverse of a function, it is necessary to solve for x and exchange the variables.
Sugars and starches are, in fact, not lipids, but rather carbohydrates. Of the four biological macro molecules (carbohydrates/polysaccharides, proteins, nucleic acids, and lip â¦ ids), lipids are hydrophobic (not water soluble), less easily metabolized, and waxy or slippery to the touch.hey are examples of organic compounds called carbohydrates... carbohydrates can be complex like polysaccharides..example is starch. or carbohydrates can simple like monosacch â¦ arides or disaccharides...example is sugar.
Starches are found in plant-based foods, such as rice, potatoes, beans, and grains. Fiber is found in a variety of fruits, vegetables, and whole grains. Not all carbohydrates convert immediately to sugar, or more accurately, to blood glucose.
