Question 1210356
.
Find the range of
f(sqrt(x)) = x + 1.
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
In order for ' f ' in the left side be a function of real argument, {{{sqrt(x)}}} must be defined.

It requires for ' x ' to be a non-negative real number  x >= 0.


So, the domain of the function in the left side is the set  { x >= 0 }.


Then the range is the set of all real numbers  { y >= 1 }.    <<<---=== <U>ANSWER</U>
