All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c\) is a smooth curve with one turning point. The turning ...

have the same curve only shifted along the x-axis have an amplitude (half the distance between the maximum and minimum values) of 1 have a period (size of one wave) of 360˚ ...

A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a large number of set intervals, it is ...

This study is an attempt to analyze students' construction of function based problem solving methods in introductory algebra. It claims that for functions to be a main concept for learning school ...

Proceedings of the American Mathematical Society, Vol. 135, No. 7 (Jul., 2007), pp. 1993-2002 (10 pages) It is a conjecture due to M. E. Rossi that the Hilbert function of a one-dimensional Gorenstein ...

second edition of this book differs from the first in many respects. The number of pages has been increased from 188 to 348, and the explanatory matter is now in both German and English. There are now ...
