It is common for emetophobics to be underweight, or even anorexic, due to strict diets and restrictions they make for themselves. The thought of someone possibly vomiting can cause the phobic
Continuous function sudden jump in function values. Similarly, the signum or sign function is discontinuous at formula_74 but continuous everywhere else. Yet another example: the function is continuous everywhere apart from formula_74. Besides plausible continuities and discontinuities like above, there are also functions with a behavior, often coined pathological, for example, Thomae's function, is continuous at all irrational numbers and discontinuous at all rational numbers. In a similar vein, Dirichlet's function, the indicator function for the set of rational numbers, is nowhere continuous. The intermediate value theorem is an existence theorem, based on the real number property of completeness, and states: For
