The answer to this question is the first and the last option.
If we consider the function
then we have this:
It does not decrease in all its domain, in fact, the function is increasing, because its slope is positive.
It is not an even function because
, therefore it is not symmetric with respect to the vertical axis.
His domain, being a straight, not bounded, is all real numbers.
The final behavior of f (x) tends to infinity in the same way that x tends to infinity
