Answer:
.
Step-by-step explanation:
From Mathematics we remember that the domain of a functions corresponds to the set of values of the independent variable ( in this case) so that images exist and the range of a function is the set of images.
In this case, we know the domain and range of and we must find the domain and range of
.
Domain
The domain of is the domain of
. That is,
.
Range
We have to define the bounds of the range of , given that range
is modified by streching and horizontal translation operations:
Lower bound ()
Upper bound ()
In consequence, the range of is
