A science class performs an experiment comparing the quantity of food consumed by a species of moth with the quantity of food supplied. The model for the experimental data is
y = 1.568x - 0.001 / 6.360x + 1, x > 0
Where x is the quantity (in milligrams) of food supplied and y is the quantity (in milligrams) of food consumed.
(a) Use a graphing utility to graph this model.
(b) At what level of consumption will the moth become satiated?
