Let

x--------> original image

y-------> modified image

F------> scale factor

we know that


y=Fx\\ \\F= (y)/(x)

if the scale factor produce an expansion under a dilation

then


y > x


(y)/(x) > 1\\ \\F > 1

therefore

the answer is


2 and
3

There are two possible answers to the question. I am choosing between 2 and 3.

2 and 3 can be the scale factors that produces and expansion under a dilation of the original image.

The original image is represented by 1. It is a dilation if the scale factor is more than 1. The value of the scale factor will increase if the dilated image is expanded.
