The vertex form of a function is g(x) = (x-3)² +9. How does the graph of g(x) compare to the graph of the function f(x) = x²?
• g(x) is shifted 3 units left and 9 units up.
• g(x) is shifted 3 units right and 9 units up.
• g(x) is shifted 9 units left and 3 units down.
• g(x) is shifted 9 units right and 3 units down.
