Question 93497
The first one is,Solve x^2+7x-8=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.
You can graph these by finding 3 points and drawing a parabola thru them.
{{{graph(400,300,-10,10,-10,10,x^2+7x-8)}}}
Answers: x=-8 x=1
---------------------
Solve -x^2+6x-5=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.
{{{graph(400,300,-10,10,-10,10,-x^2+6x-5)}}}
Answers: x = 1 x=5
---------------------
Solve x^2+6x-2=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located.
{{{graph(400,300,-10,10,-10,10,x^2+6x-2)}}}
Answers: x between -7 and -6; x between 0 and 1
-------------------

Solve x^2-4x+3=0 by graphing.If the solutions are not exact,estimate the answers by indicating the consecutive integers between which the roots are located,
I'll leave this one to you.
