You can put this solution on YOUR website!

if you have
f%28x%29+=+sqrt%28x%5E2+%2B+16+%29
domain will be all real numbers except those which make x%5E2+%2B+16+=0
since x%5E2+%2B+16+=0 will never be equal to zero no matter what is the value o x, we can say that
domain is { all x| element of R }... (all real numbers)
