Solve quadratic equations by graphing, using square roots, factoring, completing the square or using the quadratic formula. Determine the most appropriate method by considering the particular situation. 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 »

When a quadratic function is presented in vertex form, it contains within it the coordinates of the vertex or turning point of the function. Using this as the starting point of the graphing process, it is possible to the... More »

Some ideas for algebra projects include using population studies to explain exponential functions and using blood pressure measurement data to practice plotting data with Excel and a graphing calculator. Additional proje... More »

X3y3 + z3 can be factored by using a graphing calculator or through factoring as a sum of cubes. The final answer for factoring x3y3 + z3 is (xy + z) times (x2y2 - xyz + z2). More »

Piecewise function formulas for graphing have multiple definitions of the graphed function with inequalities to define where each case is true. Piecewise functions can have discontinuous segments, which are denoted on th... More »

Finding the range of a function generally requires graphing, except in the case of horizontal lines. The range refers to all of the possible y-values in a function, which are the dependent values that come from incorpora... More »
