Question

recommending a scale factor for given shapes
the smaller star has been enlarged.
which is a good estimated scale factor, according to
your evaluation of the coordinate changes?
○ 2
○ 1.5
○ 1
○ \\(\frac{1}{2}\\)

Explanation:

Step1: Pick a key vertex

Take the rightmost vertex of the smaller star: it lies at $x=3$. The rightmost vertex of the larger star lies at $x=6$.

Step2: Calculate scale factor

Scale factor = $\frac{\text{New coordinate}}{\text{Original coordinate}}$ = $\frac{6}{3}=2$

Answer:

2
