Then the inverse is y = / 3. If you need to find the domain and range, look at the original function and its graph. The domain of the original function is the set of all allowable x-values; in this case, the function was a simple polynomial, so the domain was all real numbers.
Starch is found in potatoes, and in grains such as corn and wheat. Starch is made up of glucose repeat units. Click on the glucose to see it in 3-D. In your body, special proteins called enzymes (which are also polymers, by the way) break starch down into glucose, so your body can burn it for energy.
Polysaccharides are large molecules composed of individual monosaccharide units. A common plant polysaccharide is starch (shown in Figure 12), which is made up of many glucoses (in a polypeptide these are referred to as glucans). Two forms of polysaccharide, amylose and amylopectin makeup what we commonly call starch.
