PLEASE I NEED A LOT OF HELP IM SO CONFUSED

Please solve and do the following:

f(x) = 8x^5 + 27x^4 - 2x^3 - 0x^2 + 0x + 6

x-intercept/s and y-intercept
domain and range
relative maximum/maxima and relative minimum/minima
x-values where f(x) is increasing and decreasing
Is the function odd, even, neither? w/proof
