Answer:
option D is rational
Step-by-step explanation:
A rational number is a number that can be written in the form of fraction or integer
here in the given question
A) 1.5 + √1.5
now,
√1.5 is not rational as √1.5 = 1.2247448713915890490986420373529
hence A is not rational
b) 12 - √12
√12 is not rational as √12 = 3.4641016151377545870548926830117
hence B is not rational
c) 
here,
is not rational
D) 
now,
√25 = 5
hence,
= 
= 5
therefore,
option D is rational
Remember that f(a) is the same thing as y just about. So the y value is -2. That's the flat part of the graph about.
You need an x value that is along the flat part of the graph.
The flat part goes from x = - 1 to x = 0
You need a value between 0 and - 1. The only value there that does that is B.
I don't know why the answer was given to you as A. It is not correct. Sometimes questions are like that. There's just an error in them. Appeal it with your teacher.
