Verified Answer :

The transformation from f to g represents a stretch in the x direction by a factor of 1.59.

f(x) = √x

g(x) = √(0.4x)


g(x) = √(0.4x) = √(0.4x) = √0.4 √x

g(x) = √0.4 √x                      Recall f(x) = √x

g(x) = √0.4
f(x)


Therefore:

The transformation from f to g represents a ____√0.4______ stretch.

Hope this explains it.
