End Behavior and Graph Sketching
The end behavior of a polynomial function determines how the graph extends toward positive and negative infinity. For any polynomial : If is odd and : left end goes down, right end goes up If is odd and : left end goes up, right end goes down If is even and : both ends go up If is even and : both ends go down This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 4: Polynomial Functions.
Key Concepts
The end behavior of a polynomial function determines how the graph extends toward positive and negative infinity. For any polynomial $f(x) = a nx^n + a {n 1}x^{n 1} + ... + a 1x + a 0$: If $n$ is odd and $a n 0$: left end goes down, right end goes up If $n$ is odd and $a n < 0$: left end goes up, right end goes down If $n$ is even and $a n 0$: both ends go up If $n$ is even and $a n < 0$: both ends go down.
