Question 176980
</pre><font size=4><b>
Solving for the x-intercepts:
{{{x^2-9x+5=0}}}
By Quadraric, where---->{{{system(a=1,b=-9,c=5)}}}
{{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}
{{{x=(-(-9)+-sqrt(-9^2-4*1*5))/(2*1)}}}
{{{x=(9+-sqrt(81-20))/2=(9+-sqrt(61))/2=(9+-7.81)/2}}}
{{{x=(9+7.81)/2=16.81/2=highlight(8.405>=8.41=x)}}}
{{{x=(9-7.81)/2=1.19/2=highlight(0.60=x)}}}
Y-Intercept:
{{{f(x)=0=y=0^2-9(0)+5}}}
{{{highlight(y=5)}}}
We'll see the graph:
{{{drawing(400,400,-5,16,-16,10,grid(1),graph(400,400,-5,16,-16,10,x^2-9x+5),blue(circle(0,5,.25)),blue(circle(.6,0,.25)),blue(circle(8.4,0,.25)))}}}
Thank you,
