identify the common function and the transofrmation shown in the graph?

The question/directions for this problem are as follows: "Identify the common function and transformation shown in the graph. Write the formula for the graphed function."

I identified the common function of the graph as a square root function, the original equation of this this is : [y = rad(x)]

okay, here is the graph:

you have to write the edited graph equation huzzah! I got it wrong before (Crying)

Looks like a reflection in the y-axis therefore f(-x)

then a horizontal shift of +3 i.e f(x-3)

combine these with

thank you! but... i'm still confused?
so..

f(-x) = (rad x) -3?

so many things to combine! :S

thanks to both of you! i get it now! :)
