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 = x x+12 intercept (x, y) = relative minimum (x, y) = relative maximum (x, y) = points of inflection (x, y) = (smaller x-value) (x, y) = (larger x-value) Find the equation of the asymptote. Use a graphing utility to verify your results.
