2 answers:
Answer: enlargement
Step-by-step explanation:
A dilation is a transformation which stretches or shrinks the original shape.
It creates similar shapes but of different size.
If the scale factor is greater than 1 then the image is an a stretch or enlarged.
If the scale factor is between 0 and 1 then the image is a reduction or a shrink.
If the scale factor is 1 then the figure and the image are congruent.
The given scale factor is
Since >1 .
Therefore, the dilation is enlargement .

<u>Explanation:</u>
f(x) = 2x - 1
f(√2) = 2√2 - 1
f(1) = 2(1) - 1
= 2 - 1
= 1
f(√3) = 2√3 - 1
