Graphing Polynomial Functions

End Behavior

Determined by the leading term :

❓ Question:

Describe the end behavior of $f(x) = -2x^4 + 3x^2 - 1$

Leading term: $-2x^4$

Degree: 4 (even) Leading coefficient: -2 (negative)

For even degree with negative leading coefficient:

Left end: falls (goes to $-\infty$ )
Right end: falls (goes to )

❓ Question:

Find all zeros and their multiplicities: $f(x) = x^3(x - 2)^2(x + 1)$

❓ Question:

What is the maximum number of turning points for $f(x) = 5x^6 - 3x^4 + x^2 - 7$ ?

Solve $x^2 - 5x + 6 = 0$ .

Set each factor equal to zero:

From $x^3$ :

Zero at $x = 0$ , multiplicity 3 (odd, crosses)

From $(x - 2)^2$ :

Zero at $x = 2$ , multiplicity 2 (even, bounces)

From $(x + 1)$ :

Zero at $x = -1$ , multiplicity 1 (odd, crosses)

Answer:

$x = 0$ (mult. 3, crosses)
$x = 2$ (mult. 2, bounces)
$x = -1$ (mult. 1, crosses)

The degree of the polynomial is 6.

A polynomial of degree $n$ has at most $n - 1$ turning points.

$\text{Max turning points} = 6 - 1 = 5$

Answer: Maximum of 5 turning points
