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