Question

Which of the following scale factors will result in an enlargement?




A.

k < –1


B.

–1 < k < 0


C.

0 < k < 1


D.

k = 1

Answer 1

Hmm I would dare to say.... none of the above..?
What we were really hoping to see was,
k>1.

Anything larger than one will scale things up.
I guess k<-1 .... might be what we're looking for? :\

The `magnitude` of the k's are larger than one, which is what we're looking for.
Like if we're thinking of this in terms of a function or shape,
the negative throws it somewhere else, and then the k value makes it larger.

I dunno, weird question... not very clear.
Those are my thoughts D:
maybe it'll help.
