The graph of a polynomial function is given. P(x) = 1/9x^4 - 4/9x^3
(a) From the graph, find the x- and y-intercepts. (If an answer does not exist, enter DNE.)
x-intercepts
(x, y) = (smaller x-value)
(x, y) = (larger x-value)
y-intercept
(x, y) =
(b) Find the coordinates of all local extrema. (If an answer does not exist, enter DNE.)
local minimum
(x, y) =
local maximum
(x, y) =
