Question

TRUE or FALSE

Answer 1

The number 4 is an upper bound for the set of roots of this polynomial function.

TRUE or FALSE???

Answer 2

attacehd is the polynomial function :)

Answer 3

write out a synthetic division table like so



4 | 3 -5 -5 5 2
|
--------------------------------------------------

First step is to drop the first coefficient 3

4 | 3 -5 -5 5 2
|
--------------------------------------------------
3

Then multiply that by 4 to get 12. Write this under the first -5

4 | 3 -5 -5 5 2
| 12
--------------------------------------------------
3

Add the -5 and 12 to get 7 and write it under the 12

4 | 3 -5 -5 5 2
| 12
--------------------------------------------------
3 7

Repeat the last two steps to get

4 | 3 -5 -5 5 2
| 12 28
--------------------------------------------------
3 7 23

Keep going until the table is finished

Answer 4

4 | 3 -5 -5 5 2
| 12 28 92 388
--------------------------------------------------
3 7 23 97 390

Answer 5

is that right??

Answer 6

you got it

Answer 7

since 4 is positive and the entire bottom row is positive, this means that 4 is definitely an upper bound of the zeros of f(x).

Answer 8

so my answer is TRUE???

Answer 9

yes

Answer 10

cool! thanks! :)

Answer 11

cool! thanks! :)
