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 x-intercepts, factor if possible and set each factor equal to zero. The real solutions will show up as x-intercepts on the graph. You may need a decimal approximation in some cases if a quadratic can not be factored. To find the y-intercept, as always, let x = 0. Consider the end behavior of the "parent" quadratic and cubic graphs to sketch what your y-values will do as x gets very large or very small.
