Analyze and sketch a graph of the function. Find any intercepts, relative extrema, points of inflection, and asymptotes. (If an answer does not exist, enter DNE.) y = 6x4 + 8x3 intercept ( x, y ) = (smaller x-value) ( x, y ) = (larger x-value) relative minimum ( x , y ) = relative maximum ( x, V ) = points of inflection ( x, y ) = (smaller x-value) (x, V ) = (larger x-value) Find the equations of the asymptotes. (Enter your answers as a comma-separated list of equations.) Use a graphing utility to verify your results. y X X -2 1 - 2 -1 1 - 1 -2 -2 O O
