Answer:

Option D. [4,9]

Step-by-step explanation:

we know that

The range of a function is the complete set of all possible resulting values of the dependent variable (output values), after we have substituted the domain (input values)

In this problem we have

The domain of the function (input values or independent variable) is the interval [2,3,4]

The range of the function (output variable or dependent variable) is the interval [4,9]

For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:
$k = \frac{L1}{L2}$
Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:
$k = \frac{6}{12}$
Rewriting we have:
$k = \frac{1}{2}$
Answer:
The scale factor of dilation is given by:
$k = \frac{1}{2}$
