The graph of f(x)=x^2 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.

Answer explanation

The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f, as g(x)= f(x)-9 shifts the graph downward by 9 units.
