Functions help

f(x) = √x

Graph the following:

y = -3f(x+4)+2                                 y=f(x-4)+2

 

y=2f(-x)                                           y+1/2f(x+1)

 

 

I have a request :)

Can you do the first one by just solving the funtion as I am able to graph quadratics without help. I need the genreal idea of how to solve the function and 

can you show me how this is done in desmos to avoid further nuisances- I don't know how to add "f" in desmos

 

I'm sorry if this is much :)

Thanks so much!!
