Answer: D
Step-by-step explanation:
h(x) is f(x) for x moving 4 units right.
h(x)=f(x-4) =√(x-4)
Answer D
We have 26 letters and 10 digits.
So, we have 26 choices for the first letter, 25 choices for the second letter (we can't pick the one we already chose), and 10 choices per digit (we can always choose any digit, because we can repeat them).
This leads to a total of

possible car targs.
=(f-g)(x)
=f(x)-g(x)
=x+6-(x-6)
=x+6-x+6
=12
