Quadratic functions are among the most familiar in mathematics. The general form of a quadratic function is y = ax2 + bx + c, where a, b, and c are real valued constants, except that a cannot be 0. The graph of a quadratic function is called a...

A quadratic function, in mathematics, is a polynomial function of the form f(x)=ax^2+bx+c \,\!, where a \ne 0 \,\!. It takes its name from the Latin quadratus for square, because quadratic functions...

ELIZABETH H. SLATE [*] Parameterizations for natural exponential families (NEF's) with quadratic variance functions (QVF's) are compared according to the nearness to normality of the likelihood and posterior distribution. Nonnormality of the likelihood (posterior) is measured using two criteria. The first is...

By viewing quadratic and other second-order finite population functions as totals or means over a derived synthetic finite population, we show that the recently proposed model calibration and pseudoempirical likelihood methods for effective use of auxiliary information from survey data can be readily extended...

Attempts to conduct an experiment relating to how the wing length of a whirlybird effects its time of flight. Also to model quadratic equations that can describe the shape and interpret the meaning of the plotted data, lengths and average times.
