This is a question about the composition of functions and how to get a domain function.
Given
and
.
We will form (b o a)(x) and then determine the domain.
<u>Step-1</u>

Replace each appearance of x in b(x) with
.

Thus, 
<u>Step-2</u>
To be defined, the value under the radical sign must not be negative. Therefore, the domain of
are processed as follows.

Both sides added by 3.

Both sides divided by 3.

Thus, the domain of
is

Step-by-step explanation:
<h2>Answer:-</h2><h3>Given ,</h3>
The figure is Similar.
Observation:-
Similar figures have similar sides. If we see carefully in smaller triangle, 3 has been added to each side and they are similar. We need to find y.
We have :-
5+3=8 as similar sides.
So, applying same algorithm,



is the answer.
