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.
â¢ Starch is a complex carbohydrate, whereas sugar is a simple carbohydrate. â¢ Starch is made up of long chains of simple sugar called glucose, whereas sugar can be made up of either a single sugar molecule or two simple sugar molecules linking together by a glycosidic bond.tarch vs Sugar. Starch and sugars are two types of carbohydrates found in food. Carbohydrates are the organic compounds, made up of carbon (c), hydrogen (H), and oxygen (O) in the ratio of one oxygen atom and two hydrogen atoms for every one carbon atom (CH 2 O).
