The graph of a quadratic function is shown on the grid. Which function is best represented by the graph?

• h(x) = x² - 3x - 9

• h(x) = x² + 3x - 9

• h(x) = x² - 6x

• h(x) = x² + 6x

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 a quadratic function is shown on the grid. Which coordinates best represent the vertex of the graph?
