Question

How do you find the upper and lower bounds of a polynomial?

Answer 1

For example, f(x) = 3x3 – 10x2 + 22x – 4.

Answer 2

Least Upper Bound and Greatest Lower Bound ?

Answer 3

Yeah.

Answer 4

as much as that's true, the question says to : determine between which consecutive integers the real zeros of each function are located.

Answer 5

using the upper bound theorem, and f(x)/(x-c), but i don't know what c is.

Answer 6

Are You Allowed To Use A Calculator ?

Answer 7

yeah.

Answer 8

You should have just mentioned what the original question was to begin with

Answer 9

. Plug in consecutive integers for x. The answer will be the two integers in which one gives you a positive value and one gives you a negative value. Start by trying the integers -3,-2,-1,0,1,2,3 for x.

Answer 10

I can't understand why people think it is a good idea to ask half of the question rather then simply post the entire question. That's like giving partial info.

Answer 11

LoL

Answer 12

sorry @hero. I found the terminology confusing and thought people would understand upper bound meant the theorem.

Answer 13

If You Have A Calculator You Can Find The Zero :)

Answer 14

You mean you assumed that everyone else besides you were aware that such a theorem exists?

Answer 15

yep. oops. but thanks @hba. i think i got it.

Answer 16

Your Welcome :)
