shift 4 units left, reflect over the x-axis, shift 2 units down
shift 4 units left, reflect over the y-axis, shift 2 units down
shift 4 units right, reflect over the x-axis, shift 2 units down
shift 4 units right, reflect over the y-axis, shift 2 units down

Answer: First option.

Explanation:

Below are some transformations for a function
f(x):

1. If
f(x)+k, the function is shifted "k" units up.

2 If
f(x)-k, the function is shifted "k" units down.

3. If
f(x-k), the function is shifted "k" units right.

4. If
f(x+k), the function is shifted "k" units left.

5. If
-f(x), the function is reflected over the x-axis.

6. If
f(-x), the function is reflected over the y-axis.

Then, given the parent function
f(x):


f(x)=2^x

And knowing that the the other function is:


g(x)=-2^((x+4))-2

You can identify that the function
g(x) is obtained by:

- Shifting the function
f(x) 4 units left.

- Reflecting the function
f(x) 4 over the x-axis.

- Shifting the function
f(x) 2 units down.
