Graphing a Polynomial Function
To sketch the graph of a polynomial function we need to consider the following:
A. leading term
B. behavior of the graph
The graph of a polynomial function:
1. comes down from the extreme left and goes up to the extreme right if n is even and an>0.
2. comes up from the extreme left and goes up to the extreme right if n is odd and an>0.
3. comes up from the extreme left and goes down to the extreme right if n is even and an<0.
4. comes down from the extreme left and goes down to the extreme right if n is odd and an<0.
a>0
a <0
n is even
n is odd
~ ~
C. x-intercepts
D. multiplicity of roots
If r is a zero of odd multiplicity, the graph of P(x) crosses the x-axis at r.
if r is a zero of even multiplicity, the graph of P(x) is tangent to the x-axis at r.
E.y-intercept
F. number of turning points
Turning points are points where the graph from increasing to decreasing function value, or vice versa. The number of turning points
in the graph of a polynomial is strictly less than the degree of the polynomial. Also, we must note that;
1. Quartic Functions: have an odd number of turning points; at most 3 turning points
2. Quintic functions: have an even number of turning points, at most 4 turning points
3. The number of turning points is at most (n-1).
