Suppose that f(x)=x3 and g(x)=-3x3. which statement best compares the graph of g(x) with the graph f(x)? the graph of g(x) is the graph of f(x) flipped over the x-axis and compressed vertically. the graph of g(x) is the graph of f(x) flipped over the y-axis and compressed vertically. the graph of g(x) is the graph of f(x) flipped over the y-axis and stretched vertically. the graph of g(x) is the graph of f(x) flipped over the x-axis and stretched vertically.
