Please help me answer these questions about root functions. (See attatched Picture).

horizontal shift 1 unit left

vertical shift  down two units

Domain of graph g is x≥ -1 or [-1,∞)

Range y ≥ -2 [-2,∞)

minimum (-1,-2)

2- h(x)=√x+3 is horizontally translation to the left and not the right it has to be √x-3.

3- f(1)= 4*1 = 4  y1

 f(4)= 4*4 =16    y2

step 2 : f(4)-f(1)/4-1 = y2-y1/x2-x1 = 16-4/4-1=12/3=4

the average rate of f(x)=√4x is 4
