Examples
f(x)=x4-6f(x)=x4−6
Step 1
Step 1.1
Identify the exponents on the variables in each term, and add them together to find the degree of each term.
x4→4x4→4
-6→0−6→0
Step 1.2
The largest exponent is the degree of the polynomial.
44
44
Step 2
Since the degree is even, the ends of the function will point in the same direction.
Even
Step 3
Step 3.1
The leading term in a polynomial is the term with the highest degree.
x4x4
Step 3.2
The leading coefficient in a polynomial is the coefficient of the leading term.
11
11
Step 4
Since the leading coefficient is positive, the graph rises to the right.
Positive
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.
Rises to the left and rises to the right
