Find the Bounds on the real zeros
posted by Armando on .
Find the bounds on the real zeros of the following function. Please show all of your work.
f(x)= x^4 + 5x^3 + 6x^2  4.

my question is, what does "bound" mean?

is this the same as the vertical asymptote, if not how is different?

The roots of your function are not rational
I used this source to approximate
http://xrjunque.nom.es/precis/rootfinder.aspx
(enter the expression x^4 + 5x^3 + 6x^2  4 in the input box )
x = appr.  3.29 and x = appr. 0.64
with two additional complex roots.
I don't know what "bounds of the real zeros" means, have never seen a question worded like that before.
