What is a possible graph of f(x) = ax^3 + bx^2 + cx + d?

I know x^2 is a parabola, and x^3 is.. well.. something that is nameless from what I know. I know what it is, though.

Any graphs would be great, thanks!

Earth is a planet and It has a surface, right? So does Mars!

Then why is Jupiter a planet when it doesn't have a surface as it's all gas?

Then they say that Pluto isn't a planet anymore - even though it has a surface and goes around the sun like all the others.

Can anyone explain this to me? And there are other planets with no surface!

What is the qualifications you need to become a planet?

A person stands in stationary canoe and throws a 5.00-kg stone with a velocity of 8.00 m/s at an angle of 30 degrees above the horizontal. The person and canoe have a combined mass of 105 kg. Ignoring air resistance and effects of the water, find the horizontal recoil velocity (magnitude and direction) of the canoe.
