The first two numbers are rational, because they are rational numbers with a finite number of decimal digits.
The third number is also rational, because , which is integer, and thus rational as well.
We can't say that the fourth number is rational, because we don't know how the number continues. A decimal number is rational if its decimal digits are finitely many, or if they show some periodicity. This doesn't seem the case, so the number may be irrational.
The last number is rational, because it is a periodic decimal number, and as such it admits a fraction that generates it.
Given:
The parent function is:
The other function is:
To find:
The statement that describes a key feature of function g.
Solution:
We have,
Using these two functions, we get
Putting , we get
The y-intercept of the function g at (0,2). So, option A is correct and option B is incorrect.
We know that as
and it will never intersect the line
. It means the horizontal asymptote of the function g is
Therefore, the correct option is A.
