    Thanks for the help.

    so lets start with the basic function h(x) =\sqrt{x}

    Then h(x+2)=\sqrt{x+2} This shifts the graph two units to the left on the x axis.

    finally f(x)=h(x+2)+3 the + 3 shifts the graph up 3 units in the y direction.

    see the attached graph.

    This should help with the second part as well

    the problem says -3 so would that just shift it down 3 units then?
