Question 173627
Remember------->{{{system(a=2,b=-4,c=6)}}}
For the x-intercept:
{{{x=b/(-2a)=-4/(-2*2)=-4/-4=highlight(1=x)}}}
For "y", solve function {{{f(1)}}}:
{{{y=f(1)=2*1^1-4*1+6=2-4+6=highlight(4=y)}}}
See graph,

{{{drawing(400,400,-10,10,-10,10,grid(1),graph(400,400,-10,10,-10,10,2x^2-4x+6),circle(1,4,.15))}}}
Thank you,
