Select the following expressions. I will just list the letter choice:
A, C, D
Answer:
<u>It</u><u> </u><u>is</u><u> </u>
<u>
</u>
Step-by-step explanation:

If the function is: f(x) = 4^x - 8
D = {XeR}
R = {YeR|Y≥0}
if the function is: <span>f(x)=4^(x-8)
</span>D = {XeR}
R = {YeR|Y≥ -8}
It is 8 because you would do 9x8=72
