See explanation below

Explanation:

We go from y=sqrtx

to y=-2sqrt(3(x-4))+9

We compare this to

y=asqrt(b(x+c))+d

a=-2 flips the graph upside down

b=3 horizontal stretch

c=-4 horizontal shift to the right

d=9 vertical shift up

graph{(y-sqrtx)(y+2sqrt(3(x-4))-9)=0 [-14.59, 36.74, -5.92, 19.75]}
