Give the equation of the function whose graph is described.The graph of y = x2 is shifted 2 units to the right. This graph is then vertically stretched by a factor of 6 and reflected across the x-axis. Finally, the graph is shifted 7 units upward.
A. y = -6(x + 2)2 + 7 B. y = -6(x - 2)2 - 7 C. y = -6(x + 7)2 + 2 D. y = -6(x - 2)2 + 7
