Slide 5:
The general square root function is
y = a x-h + k
Shortcut to graphing:
-Start at (h, k)
-go to the right by one and up/down by a
Slide 6:
y = 2 x+3 -1 (-3, -1) (-2, 1)
Slide 7:
The general square root function is
y = a 3 x-h + k
Shortcut to graphing:
-Start at (h, k)
-go to the right by one and up/down by a
-go to the left by one and up/down by the opposite of a.
