Question 660836


make a table first, find several points (x,y), plot them on Cartesian coordinate system and draw a graph

{{{x}}}|{{{y}}}
{{{0}}}|{{{1,41}}}.......{{{ y= sqrt ( 0+2 )}}}..{{{ y= sqrt ( 2 )=1.41}}}
{{{-1}}}|{{{1}}}.....{{{ y= sqrt ( -1+2 )}}}..{{{ y= sqrt ( 1 )=1}}}
{{{-2}}}|{{{0}}}.....{{{ y= sqrt ( -2+2 )}}}..{{{ y= sqrt ( 0 )=0}}}
{{{2}}}|{{{2}}}.....{{{ y= sqrt ( 2+2 )}}}..{{{ y= sqrt ( 4 )=2}}}
{{{7}}}|{{{3}}}.....{{{ y= sqrt ( 7+2 )}}}..{{{ y= sqrt ( 9 )=3}}}
{{{14}}}|{{{4}}}.....{{{ y= sqrt ( 14+2 )}}}..{{{ y= sqrt ( 16 )=4}}}

it should look like this:

{{{ graph( 600, 600, -10, 10, -10, 10,  sqrt ( x+2 )) }}}
