WOW! that is a lot of info but i really appreciate taking time to hep me, i went through and double checked your work and it all looks good . This makes sense! Thank you so much .

what do you think about that ?

Awesome! Thank you

thank you!

Awesome, so I inputted it correct?

Manu evaluates  f(-4)  and determines its value to be  -4 . Manu concludes that x + 4 is not a factor of f(x)=−x^4−6x^3+15x−72 .

If you click on this link the upper boun therm states "by using synthetic divsion if alll numbers are postitive and then thats the upper bound "

When i solve 7 into the equation so 7/4 -25 -5 -13 , i got all postitive values and then once i do 6 it is a mis of pos and neg values

Is it possible for it to be 7 ? Because when I didive 7 by the polyonmial I get all postitive values and that is lower than 7.25?

do you have any ideas?

Cphil, isnt here to help me since that link was from earlier but i beilieve the answer is actually 13

thanks for your help! I found out that the answer for the last one was actaully postitive infinty as well. Just ated to let you know so you can make  note of it.Thanks again though for your help i aprreacite it.

f(x)  =  2x^4 + 6x^2 + 4

The lead coefficient is positive and the power on its associated variable is even

The polynomial will approach + infinity   as x → infinity  and as x →  infinity
