Question

Describe the transformation of the graph of f into the graph of g as either a horizontal or vertical stretch.
f(x) = sqrt(x)
g(x) = sqrt(0.5x)

Answer 1

let's consider the point x=4, then we have:
f(4)=2
g(4)=sqrt(2)
so the ratio, is:
f(4)/g(4)=sqrt(2)
furthermore, if x=9
we can write:
f(9)=3, and
g(9)=3/(sqrt(2)
and the ratio is
f(9)/g(9)=sqrt(2)

Answer 2

so, we have a vertical stretch

Answer 3

Ok would that be all for the question?

Answer 4

yes!
