You can put this solution on YOUR website!
if you have:
f%28x%29=-sqrt%28x%29%2B1
domain will be:
{ x element R : x%3E=0 } (all non-negative real numbers)
range:
{ f%28x%29 element R : f%28x%29%3C=1 }
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+-%28sqrt%28x%29%29%2B1%29+
but,if you have:
f%28x%29=-sqrt%28x%2B1%29
domain will be:
{ x element R : x%3E=-1 } (all non-negative real numbers)
{ f%28x%29 element R : f%28x%29%3C=0} (all non-positive real numbers)
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+-%28sqrt%28x%2B1%29%29%29+
