Domain: All Real Numbers
Range: All Real Numbers
Further explanation:
Let us define domain and range first
Domain is the set of all possible inputs for a function on which the function is defined.
While range is the output of the function obtained by inputting domain
Here,
Given function is:
The function will not be undefined on any input, so the domain of the function is all real numbers.
Similarly, the range will also be all real numbers as there is no input which makes it undefined.
Keywords: Domain, range of a function

Please find the attachment for a better understanding of the explanation to this question.
As we can see from the diagram attached, the X axis represented by XX' and the Y axis represented by YY' intersect each other at the origin represented by O. Further, we notice that this intersection is at the angle 90 degrees or in other words the intersection is perpendicular. Thus, we have seen that the the x and y axes in the xy plane intersect perpendicularly. And hence, the answer is TRUE.
Please note that this is always the case and this is also known as orthogonality.
