Are you trying to solve those questions before sending them here?

here's a method for finding end behaviors:

When we have a polynomial P(x)=a_{n}*x^{n}+...+a_{0} and we want to find the end behaviors of the polynomial, we can instead find the end behaviors of the polynomial a_{n}*x^{n}. __The end behaviors will stay the same.__

for example: if the polynomial is 2x^{4}+x^{3}+1 and we want to find the end behaviors we can replace the polynomial with the polynomial 2x^{4} and find the end behaviors for this polynomial instead.

PLEASE try solving this question, at least try to solve the end behavior part.

wow...I am trying to solve them. I always do. I just don't put my answers because I know they will end up being wrong and I'll look dumb.

She's trying as hard as she can to understand this stuff....maybe she is home-schooled...if so....I can see why it's difficult !!!

Don't judge someone until you have walked in their shoes......

No one is going to think that your answers are dumb. However, some people might think that you're lazy.

Here's another tip for finding end behaviors:

when the polynomial is with degree n larger than 0 and the leading coefficient is b, then:

the end behavior in infinity will be +infinity if b is positive and -infinity if b is negative

the end behavior in minus infinity will be +infinity if b is negative and n is odd or if b is positive and n is even, and -infinity otherwise (when b is positive and n is odd and when b is negative and n is even)

Domain, Range : (-inf, inf)

Relative max : (0,6)

Relative min : (2.333, - 6.704)

End behavior : - inf at left end.....+ inf at right end

Increasing intervals = (-inf, 0) U (2.333, inf)

Decreasing interval = (0, 2.333)

Thanks ^-^ the only thing I actually get right is the domain and range lol and sometimes the end behavior
