Alissa is currently a teacher in the San Francisco Bay Area and Brightstorm users love her clear, concise explanations of tough concepts
To graph a cubic or quadratic function, you'll want to know as many key features as possible, including x and y intercepts and end behavior. To find the xintercepts, factor if possible and set each factor equal to zero. The real solutions will show up as xintercepts on the graph. You may need a decimal approximation in some cases if a quadratic can not be factored. To find the yintercept, as always, let x = 0. Consider the end behavior of the "parent" quadratic and cubic graphs to sketch what your yvalues will do as x gets very large or very small.
