An experiment in which subjects do not know if they have been given an active treatment or a placebo
An arrangement of elements of a set, in which order is not important
Endpoint of an interval
A real number that represents one “end” of an interval.
Increasing on an interval
A function ƒ is increasing on an interval I if, for any two points in I, a positive change in x results in a positive change in.
Inverse reflection principle
If the graph of a relation is reflected across the line y = x , the graph of the inverse relation results.
