Find the End Behavior 6x^9+4x^6+2x^4-200

$6 x^{9} + 4 x^{6} + 2 x^{4} - 200$

Step 1

Write $6 x^{9} + 4 x^{6} + 2 x^{4} - 200$ as a function.

$f (x) = 6 x^{9} + 4 x^{6} + 2 x^{4} - 200$

Step 2

Identify the degree of the function.

Identify the exponents on the variables in each term, and add them together to find the degree of each term.

$6 x^{9} \to 9$

$4 x^{6} \to 6$

$2 x^{4} \to 4$

$- 200 \to 0$

The largest exponent is the degree of the polynomial.

$9$

Step 3

Since the degree is odd, the ends of the function will point in the opposite directions.

Odd

Step 4

Identify the leading coefficient.

The leading term in a polynomial is the term with the highest degree.

$6 x^{9}$

The leading coefficient in a polynomial is the coefficient of the leading term.

$6$

Step 5

Since the leading coefficient is positive, the graph rises to the right.

Positive

Step 6

Use the degree of the function, as well as the sign of the leading coefficient to determine the behavior.

1. Even and Positive: Rises to the left and rises to the right.

2. Even and Negative: Falls to the left and falls to the right.

3. Odd and Positive: Falls to the left and rises to the right.

4. Odd and Negative: Rises to the left and falls to the right

Step 7

Determine the behavior.

Falls to the left and rises to the right
