The graph of the function:
f(x)=<span>x3 – 2x2 – 19x + 20 is as shown in the figure below:
The domain are all real numbers
The range are all real numbers
Thus the statements that hold are:
</span><span>2.As x approaches negative infinity, y approaches negative infinity.
</span><span>3.The domain of the function is all real numbers.
</span><span>5.The graph has a positive y-intercept.</span>
