Give the equation of the function g whose graph is described.The graph of f(x) = ?x? is vertically stretched by a factor of 4.8. This graph is then reflected across the x-axis. Finally, the graph is shifted 0.3 units downward.
A. g(x) = -4.8?x? - 0.3 B. g(x) = 4.8?x - 0.3? C. g(x) = 4.8?x? - 0.3 D. g(x) = 4.8?-x? - 0.3
