Step-by-step explanation:
A function f(x) can be scaled by a factor of "a" and translated by (h,k) by the relation:
f(x) -> a f(x-h)+k
substitute f(x) by sqrt(x), then
sqrt(x) -> a*sqrt(x-h) + k
So the given equation is derived from f(x) = sqrt(x), hence a radical function.
Yes
hope this is understandably sure right easy for you
Step-by-step explanation:

You would divide 10.45 by .55 and you would get 19 so 19 is your answer hope this helps
