Question 765309: (x)=2x^4+4x^3-7x^2-x+7 has no rational roots
use a graphing calculator to approximate the irrational solutions correct to 3 decimals
if there is more than 1 real solution, write your answers from smallest to largest
my own graphing calculator is broken and the online calculators I use don't give me the accurate answers I need to submit. (i'm taking an online math course and it is very strict on how I submit my answers)
can you solve this for me please?? thank you so much

You can put this solution on YOUR website! Use google search engine and enter your equation in text form, just as you (almost) have it. Start by saying either "f(x)=...." or "y=...", and then your polynomial. Click on the GO button of your browser. You should see a link, maybe even the actual graph, shown in the search listings, and near the top.
Some other search engines will give you results like that also.
