What is the leading coefficient, degree, and end behavior #P(x)=-4x^2-3x^3+2x^2+4#?
1 Answer
Please see the explanation below:
Explanation:
simplify and rewrite in standard form:
The leading coefficient is:
The degree of the polynomial is the highest power of any variable, so in this case we have a 3rd degree polynomial hence:
the degree =
The end behavior of the graph of a function is determined by its degree and the sign of its leading coefficient, as follows:
1)Even power with positive leading coefficient: up on both ends.
2)Even power with negative leading coefficient: down on both ends.
3)Odd power with positive leading coefficient: down on left side , up on right side.
4)Odd power with negative leading coefficient: up on left side , down on right side.
So in this case #4 applies:
up on left side , down on right side
