Answer:

a = -2, h = 2, k = 1

Explanation:

Compare the expressions. Match one pattern to the other.


f(x)=-2|x-2|+1\\\\f(x)=\ \,\,a|x-h|+k \qquad\ a=-2,\ h=2,\ k=1

__

The transformations are ...

Translation by (h, k) = (2, 1). That is, 2 units right and 1 unit up.

Vertical scaling by "a", which is (i) reflection over the x-axis (because a < 0), and (ii) expansion by a factor of 2.

A table and graph are shown in the attachment.
