Answer:
a) g(x) = (x - 3)^3
Explanation:
because the function has shifted horizontally to the right 3 units, the 3 has to be within the parentheses. additionally, because it's moved to the right 3 units, the term inside the parentheses is -3. you would think it'd be +3, but it's actually the other way around. i hope this helps! :)
