Question 950116: How to left where the graph is coming from?
P(x)=x(x^2-4)
I know the y-int is (0,0
and x-int is (2,0),(-2,0)
How do i know if the graph is coming from the bottom from the left/right or from the top left/right?
Please help me understand
Thank you!

When x is very large in the negative range, the first term is negative, the second term is positive, so the value of P%28x%29 will be negative.
When x is very large in the positive range, the first term is positive, the second term is also positive, so the value of P%28x%29 will be negative.
So the graph will come from the bottom, left, cross through the x axis at -2,0,and 2 and then will move up to the top, right.
