The y-intercept is the point in a function where the value of the x-coordinate is zero. By definition, a function has only one y-intercept. The x-intercept is the point in a function where the value of the y-coordinate i... More »

A quadratic function is a function of the form f(x) = ax^2 + bx + c where a, b and c are constants. Part of the definition of a quadratic function is that a is not equal to zero, although b and c can equal zero. More »

The y axis is typically the vertical axis in a two-dimensional coordinate system. The y coordinate is measured along this axis. It is crossed by, or perpendicular to, the horizontal x axis. More »

Some examples of mathematical expressions include "mx + y," "5 /a," "20" and "6 - 4." Mathematical expressions are groups of variables, constants and operators that represent values. More »
