anonymous · Answer

$$f(x)=-3x^5-5x^3+5x^2$$
Looks like a polynomial function of 5th degree to me.

anonymous · Answer

thank you so much can u explain to me how you got tht

anonymous · Answer

Sort the polynomial function by the exponentials, the degree of this polynomial would be the highest exponent involved.

For very large numbers of x, all the remaining terms would become significantly small compared to this leading term, hence redundant.

anonymous · Answer

wat about x4 + 3x2 -5x and 5x3y2 + 13x4y3-17x3y4 ?

anonymous · Answer

so in this one x4 + 3x2 -5x it would be 4?

anonymous · Answer

This function doesn't look like a traditional polynomial to me, because a polynomial is a function of x and the one you just posted is a function of x,y. Therefore it is multivariable.

anonymous · Answer

so it would be not a polynomial function in 1 variable?

anonymous · Answer

A polynomial function looks like this:

$$ f(x)=a_nx^n+a_{n-1}x^{n-1}+ \cdots + a_1x +a_0 $$
So I agree to your statement, it is not a polynomial function in 1 variable, hence I don't see it as necessary to classify it that way.

anonymous · Answer

ohk and the second one i put up after that would be 4 rite?

anonymous · Answer

$$f(x)=6x^{5}+2x^2+4x+3 $$ 
would be a polynomial of of fifth degree.

anonymous · Answer

yes exactly, 4. The one you posted.

anonymous · Answer

yay!!! this is easy!! lol thanks so much!

hehe, you are very welcome.
