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.
It is the most common carbohydrate in human diets and is contained in large amounts in staple foods such as potatoes, wheat, maize (corn), rice, and cassava. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight.
