Answer:

Options C and D.

Step-by-step explanation:

The given functions are

[tex]f(x)=2^{x-6}+3[/tex]

[tex]g(x)=2^{x-3}+2[/tex]

We need to find the transformation from f(x) to g(x).

Now, write the function g(x) in the form of f(x).

[tex]g(x)=2^{x+3-3-3}+2+1-1[/tex]

[tex]g(x)=[2^{(x+3)-6}+3]-1[/tex]

[tex]g(x)=f(x+3)-1[/tex]     ...(1)

The translation is defined as

[tex]g(x)=f(x+a)+b[/tex]                .... (2)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

From (1) and (2), we get

[tex]a=3>0[/tex], so graph shifts 3 units left.

[tex]b=-1<0[/tex], so graph shifts 1 unit down.

Therefore, the correct options are C and D.
