Write an equation for a function whose graph fits the given description. 20) The graph of f(x) = x2 is shifted 2 units to the left. This graph is then vertically stretched by a factor of 6 and reflected across the x-axis. Finally, the graph is shifted 8 units downward. A) y =-6(x - 2)2 + 8 B) y =-6(x -2)2 - 8 Cy = - 6(x + 8)2- 2 *D) y =-6(x + 2)2 - 8
