Real Function

If f(x) =in (x2+7|x|10) is a single valued real function then the range of f(x) in its natural domain will be

f(x) = ln (x2 +7 │x│+ 10 )
x2 +7x +10 > 0
x > 0 = ( x+2 ) * ( x+ 5 ) 
(x + 2) (x + 5) > 0
X π 5 ( 7- 3 ) = > 0 
f ( x ) = 2x + 7 = 0 
Therefore it can be said that the sum is a single domain.
