Question 1181890


{{{f(x) = sqrt(x+4)-4}}}

choose some values for {{{x}}}, make a table
{{{x}}}|{{{f(x) }}}

{{{-2}}}|{{{-2.6}}}.......................{{{f(-2) = sqrt(-2+4)-4=sqrt(2)-4=-2.6}}}
{{{0}}}|{{{-2}}} .......................{{{f(0) = sqrt(0+4)-4=2-4=-2 }}}
{{{2}}}|{{{-1.6}}}.......................{{{f(2) = sqrt(2+4)-4=sqrt(6)-4=-1.6}}}
{{{5}}}|{{{-1}}}.......................{{{f(5) = sqrt(5+4)-4=sqrt(5)-4=3-4=-1}}}

plot these points and draw a graph


{{{ drawing( 600, 600, -10, 10, -10, 10,
circle(-2,-2.6,.12), locate(-2,-2.6,p(-2,-2.6)),
circle(0,-2,.12), locate(0,-2,p(0,-2)),
circle(2,-1.6,.12), locate(2,-1.6,p(2,-1.6)),
circle(5,-1,.12), locate(5,-1,p(5,-1)),
graph( 600, 600, -10, 10, -10, 10,  sqrt(x+4)-4)) }}}
