Answer to Problem 2E
The end behavior of polynomial is
Explanation of Solution
Given information:
End behavior of the polynomial depends on the leading coefficient of the polynomial and degree of polynomial.
When the degree of polynomial is odd:
If leading co efficient is positive then
If leading co efficient is negative then
When the degree of polynomial is even:
If leading co efficient is positive then
If leading co efficient is negative then
Therefore the leading co efficient is positive odd number 1 and .
Hence , the end behavior of polynomial is,
