One more question:
Beginning with the function f(x) = (0.8)^(x), state what transformations were used on this to obtain the functions given below.
a) g(x) =  (0.8)^(x)  2
b) h(x) = (1/2) (0.8)^(x2)
c) k(x) = (0.8)^(3x+9)
These are the answers I have, (may be incorrect)
a) reflect across the horizontal axis
moved down by 2 units
b) moved right by 2 units
vertically compressed by (1/2)
c) reflect across the vertical axis
moved left by 9 units
horizontal compression by 3
Thanks.

in c) I object to your horizontal movement
k(x) = (.8)^(3x+9)
= (.8)^( 3(x3) )
so moved to the right by 3 units

Thanks, glad I can correct that!
