The parent function for the linear equation is y = x. In general terms, the parent function provides a template for the range and the domain, which holds true for other equations within the family. More »

To graph a math equation, acquire some graphing paper, draw x and y axes, and decide whether the equation is linear or non-linear. Approach the problem by finding the slope of the linear equation or using a table for a n... More »

The simplest way to graph a quadratic equation is to substitute an array of values for x in the equation and solve for y in each case to obtain several (x,y) coordinates. After obtaining the coordinates, they can be plot... More »

A rational parent function is the most basic rational function whose form is imitated by all other rational functions, and it is written as f(x) = 1 / x. Rational functions represent the division of two polynomials where... More »

Solve quadratic function word problems by determining each term of the quadratic equation and then solving for x when the equation is equal to zero. A quadratic equation is expressed as ax^2 + bx + c = 0 when in standard... More »

An inverse equation, or inverse function, is an equation that reverses another equation. If an equation will give the value of y when providing x, the inverse equation will give the value of x when providing y. More »

Change a quadratic function to its vertex form by applying a process called completing the square, then isolate the y variable on one side of the equation. The vertex form is represented by the formula y = a(x-h)^2 + k, ... More »
