Question

use synthetic division to verify the upper bound f(x)=4x^4+4x^2+2x-3

Answer 1

what value do they give to verify ?

Answer 2

i see its missing a x^3 term, so make sure to include it in the process as +0x^3

Answer 3

and ... x^4 has no upper bound, as x gets larger, so does the value of the function

Answer 4

or, is the UB defined by the given f(x)?

Answer 5

that's the entire question... Use synthetic division to verify the upper bound of ........ (has no zero greater than)

Answer 6

a function based on a positive, x^4, has no upper bound.

upper bound of the zeros? just sounds odd since the x axis is a left to right not an up and down

Answer 8

but if all you are doing is trying to define the roots ...

Answer 9

the link would suggest that they give you an x value to verify with ... your post provides nothing to test out
