Module 4 Test Remediation

Front

List the zeros for the function f(x)=(x+4)(x-3)(x-2).

Back

The zeros are x=-4, x=3, x=2.

Front

Describe the end behavior of f(x) = -5x^4 - 2x^2 + 8.

Back

Left side: Falls, Right side: Falls.

Front

How does a factor with multiplicity of 2 affect the graph of a polynomial function?

Back

It causes the graph to 'Touch and Turn' at the x-intercept.

Front

Which interval best reflects an interval of increase on the graph shown?

Back

The interval of increase is (-2, 0).

Front

The degree of a polynomial determines...

Back

The maximum number of x-intercepts.

Front

What is a polynomial function?

Back

A function that can be expressed in the form f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n ≠ 0.

Front

What is the leading coefficient of a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree.

Front

What does the term 'turning point' refer to in a polynomial graph?

Back

A turning point is where the graph changes direction from increasing to decreasing or vice versa.

Front

What is the significance of the y-intercept in a polynomial function?

Back

The y-intercept is the value of the function when x=0, indicating where the graph crosses the y-axis.

Front

How do you determine the maximum number of turning points in a polynomial function?

Back

The maximum number of turning points is one less than the degree of the polynomial.
