The graph of f(x) = x² was transformed to create the graph of g(x) = f(x) – 9. Which statement about the graphs is true?

• The graph of g is a reflection of the graph of f across the x-axis.

• The vertex of the graph of g is 9 units to the right of the vertex of the graph of f.

• The graph of g is a reflection of the graph of f across the y-axis.

• The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.

The graph of f(x) = x² was translated 4.5 units to the left to create the graph of function g. Which function represents g?
