Answer:
All Real x larger or equal zero
or in inequality form:
or in interval notation:
Step-by-step explanation:
If and
, then using the definition for the composition of functions
, we get:
Base on this final expression, we understand that the Domain (numbers that can be used as input of the function and produce a real number as result) of this new function is limited to those x-values larger than or equal to zero. Negative numbers inside the square root will not produce a real number.
Therefore, the Domain is restricted to All Real numbers larger than or equal to o (zero).
This statement can also be given in inequality form as
or in interval notation:
