In mathematics, a power function is a function of the form f(x) = cxa, where c and a are constant real numbers and x is a variable.
Power functions are a special case of power law relationships, which appear throughout mathematics and statistics.
Famous quotes containing the words power and/or function:
“an age of unscrupulous and shameless book-making, it is a duty to give notice of the rubbish that cumbers the ground. There is no credit, no real power required for this task. It is the work of an intellectual scavenger, and far from being specially honourable.”
—Richard Holt Hutton (1826–1897)
“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot function without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”
—Howard Brenton (b. 1942)
