So.......now that we know how to graph the square roots......
what can be next?

How do you think the graph of
will change . . .
Check with your calculator!!
The number underneath the radical sign will shift
the graph LEFT or RIGHT (opposite of the sign)
The number added or subtracted after the radical sign
will shift the graph UP or DOWN (same as the sign)

What about the number in front of the radical sign???
How does that change the graph of
?
The number in front of the radical sign will
STRETCH or SHRINK the graph
If |a| > 1, the graph will stretch (wider)
If |a| < 1, the graph will shrink (narrower)
If a is negative, the graph will flip
