Dr. Lipsitz "et al".'s findings also showed that those afflicted with emetophobia often have difficulties comfortably leading a normal life. Many find that they
Rational function Every polynomial function formula_37 is a rational function with formula_38 A function that cannot be written in this form, such as formula_39 is not a rational function. The adjective "irrational" is not generally used for functions. The rational function formula_40 is equal to 1 for all "x" except 0, where there is a removable singularity. The sum, product, or quotient (excepting division by the zero polynomial) of two rational functions is itself a rational function. However, the process of reduction to standard form may inadvertently result in the removal of such singularities unless care is taken. Using the definition of
