In math, a function is a statement that contains one or more variables that can be calculated to produce one or more answers. Math functions range from the simple to the complex. Evaluating a function at a particular poi... More » Math Algebra

Piecewise functions are solved by graphing the various pieces of the function separately. This is done because a piecewise function acts differently at different sections of the number line based on the x or input value. 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 »

Examples of mathematical functions include y = x + 2, f(x) = 2x, and y = 3x - 5. Any mathematical statement that relates an input to one output is a mathematical function. Many simple mathematical functions are written a... More »

To solve equations with variables on both sides, move the constants to the right side of the equation, simplify, move the variables to the left side and simplify. If the variable is negative, multiply both sides by -1 to... More »
