Question

Determine Upper and lower bounds on the zero's of f(x)=3x^(3)+x^(2)+5 I need a quick answer this has me stumped and almost out of time.

Answer 1

Do you want to find the maximum and minimum points?

Answer 2

If the third line of a synthetic division of f(x) by x - r is all positive for some r > 0, then r is an upper bound for the zeros of f(x);

Answer 3

Is that what maximum and minimum bounds are?

Answer 4

What @Luis_Rivera said :P it seems smarter than what I would've said :P

Answer 5

:) it doesn't make any more sense to me, I just don't have the foundation to even understand the problem at a basic level.

Answer 6
