Graphing polynomial functions
posted by eric on .
How do i graph the polynomial function of:
f(x)= (x+3)(x+1)(x2) squared

Graphing it on your graphing calculator?
Or
Graphing it on paper?
On paper, you have zeros at 3, 1, and at x=2 At large negative x, (check me), the fuction is positive.
At x between 3 and 1, it is negative, nad between x of 1 and 2 it is positive, and greater than two it is positive. That ought to get you started. Make a table of values to fill in the details.
The graphing calc makes all this so easy.
