Find the End Behavior f(x)=832x-4x^5+8960+122x^4-2x^6-2192x^2+60x^3

$f (x) = 832 x - 4 x^{5} + 8960 + 122 x^{4} - 2 x^{6} - 2192 x^{2} + 60 x^{3}$

Step 1

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.

$832 x \to 1$

$- 4 x^{5} \to 5$

$8960 \to 0$

$122 x^{4} \to 4$

$- 2 x^{6} \to 6$

$- 2192 x^{2} \to 2$

$60 x^{3} \to 3$

The largest exponent is the degree of the polynomial.

$6$

Step 2

Since the degree is even, the ends of the function will point in the same direction.

Even

Step 3

Identify the leading coefficient.

Simplify the polynomial, then reorder it left to right starting with the highest degree term.

Move $8960$ .

$832 x - 4 x^{5} + 122 x^{4} - 2 x^{6} - 2192 x^{2} + 60 x^{3} + 8960$

Move $832 x$ .

$- 4 x^{5} + 122 x^{4} - 2 x^{6} - 2192 x^{2} + 60 x^{3} + 832 x + 8960$

Move $- 2192 x^{2}$ .

$- 4 x^{5} + 122 x^{4} - 2 x^{6} + 60 x^{3} - 2192 x^{2} + 832 x + 8960$

Move $122 x^{4}$ .

$- 4 x^{5} - 2 x^{6} + 122 x^{4} + 60 x^{3} - 2192 x^{2} + 832 x + 8960$

Reorder $- 4 x^{5}$ and $- 2 x^{6}$ .

$- 2 x^{6} - 4 x^{5} + 122 x^{4} + 60 x^{3} - 2192 x^{2} + 832 x + 8960$

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

$- 2 x^{6}$

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

$- 2$

Step 4

Since the leading coefficient is negative, the graph falls to the right.

Negative

Step 5

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 6

Determine the behavior.

Falls to the left and falls to the right

Step 7

Find the End Behavior f(x)=832x-4x^5+8960+122x^4-2x^6-2192x^2+60x^3
