My instructor is saying that I have to do more than one graph. Can anybody help me I am lost!

**Reiny**, Friday, July 27, 2012 at 2:13pmI will assume you mean

y = -√(x-6) and NOT y = -(√x) - 6

start with y = √x

using the following points, sketch the graph.

(0,0), (1,1), (4,2), (9,3), (16,4) ...

(notice I pick numbers that work out nicely)

You will have a "swooping" curve in the first quadrant that rises slowly.

now sketch y = - √x by reflecting your graph in the x-axis, (just flip it downwards)

then move the second graph 6 units to the RIGHT

(move each point 6 units to the right)

domain: any value of x , x ≥ 6

range: any real value of y , y ≤ 0 (all below the x-axis)

To verify, enter

(x-6)^.5

in the "first graph" in

change "Range x-axis from" 6 to 20
