You can put this solution on YOUR website!
y=2sqrt%28x%2B9%29-4
find intercepts:
set x=0=>y=2sqrt%280%2B9%29-4=>y=2sqrt%289%29-4=>y=2%2A3-4=2 or y=2%2A%28-3%29-4=-10
set y=0=>0=2sqrt%28x%2B9%29-4=>4=2sqrt%28x%2B9%29=>4%2F2=sqrt%28x%2B9%29
=>2=sqrt%28x%2B9%29=>2%5E2=%28sqrt%28x%2B9%29%29%5E2=>4=x%2B9=>x=-5
make a table:
x|y
0|2
0|-10
-5|0
-9|-4...x=-9=>y=2sqrt%28-9%2B9%29-4=>y=-4
7|4...x=7=>y=2sqrt%287%2B9%29-4=>y=2%2A4-4=4
plot these points and draw a graph through


this is a real part of the graph since
domain:{ x element R : x%3E=-9 }
range:{ y element R : y%3E=-4 }
