help pleasee @Isaiah.Feynman @ilfy214 @BangkokGarrett @cwrw238 @mialovesyou03
i'm pretty rusty at this stuff - the above link should help
ok thanks
Same! I'm sorry that I can't help :(
Put it in standard form, first. This will put that -x^3 out front and you will have better information.

I can help. Look at the degree of the polynomial. The degree of a polynomial is the largest exponent in the function. In Part 1 of your example, the degree of the polynomial is 2, since the largest exponent on the variables is 2 (x^2) If the degree of the polynomial is even, the function will either approach positive infinity on both ends or negative infinity on both ends. If the coefficient of your largest degree term is positive, the function approaches positive infinity on both ends. If negative, the function approaches negative infinity on both ends
If the degree of the polynomial is odd, the function will approach positive infinity on one end and negative infinity on the other. If the coefficient of your largest degree term is negative, it approaches positive infinity to the right and negative infinity to the left. If the coefficient of your largest degree term is positive, it approaches negative infinity to the right and positive infinity to the left
thats part 1?
oh theres a neat reference table to help with this |dw:1376431191252:dw|
