Which root has even multiplicity: 1, -4, -1, or 2?

Back

The root with even multiplicity is 1.

Front

What is the factored form of the polynomial function represented by the graph?

Back

f(x) = (x+4)(x+1)²(x-2)(x-4).

Front

What determines the end behavior of a polynomial function?

Back

The end behavior is determined by the degree and the sign of the leading coefficient.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial.

Front

What does it mean for a root to have odd multiplicity?

Back

A root has odd multiplicity if it crosses the x-axis at that root, indicating a change in sign.

Front

What is the significance of the leading coefficient in a polynomial?

Back

The leading coefficient determines the direction of the graph as x approaches positive or negative infinity.

Front

How do you find the x-intercepts of a polynomial function?

Back

Set the polynomial equal to zero and solve for x.
