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 = XV 4 - x2 intercept ( x, y ) = (smallest x-value) ( x, y ) = ( x , y ) = (largest x-value) relative minimum ( x, y ) = relative maximum (x, y) = point of inflection (x, y) = Find the equations of the asymptotes. (Enter your answers as a comma-separated list of equations.)
