A polynomial function is defined by f(x)=−2(x+3)2(x−1). Which of the following describes the graph of f(x)?
The graph crosses the x-axis at x=−3 and touches the x-axis at x=1.
The graph touches the x-axis at x=−3 and crosses the x-axis at x=1.
As x→∞, f(x)→∞.
The graph has x-intercepts at x=3 and x=−1.
