In the transformation,
g(x)=a*f(x-h)+k
a stretches the parent function f(x) by a scale factor of a (a>1), or
shrinks the parent function by a factor of a (0<a<1).
It will also translate a distance of h to the RIGHT, and
a distance of k UP.
Therefore if a value of k=10, the function f(x)=sqrt(x) becomes
g(x)=sqrt(x)+10, or it is moved upwards by 10 units.
