infinity, f(x) goes to infinity.

The graph of the function crosses the x–axis at x = [___].

The graph of f(x) touches but does not crosscrossesneither crosses nor touches the x-axis at x = –3, 0, and 3.

Complete the statements about the key features of the graph of f(x) = x5 – 9x3.As x goes to negative infinity, f(x) goes to infinity, and as x goes to positive
