Ans. Given `f(x)=(.8)^x`

1.   `g(x)=-(.8)^x-2`

substitute  `(.8)^x =f(x) `  in g(x) ,we get required transformation.

`g(x)=-f(x)-2`

 

2.     Substitute  ``  in h(x) ,     we get required  

       transformation.

        h(x)=(1/2) (1/.8)^2 f(x)

              =(1/1.28) f(x)

3. Substitute  ``  in k(x) ,we get required transformation.

k(x)=(.8)^(.3x+9)

=((.8)^(x))^(.3).(.8)^9

=( f(x))^(.3). (.8)^9
