Mixed Polynomials Practice

Find the values of the zeros of the function y=(x+2)(x-3)(3x-5)

• x=-2, x=3, x=5/3

• x=2, x=-3, x= -5/3

• x=-2, x=3, x=3/5

• x=2, x=-3, x=-3/5

Which of the following is the correct equation for the function graphed? Use the zeros and their multiplicity from the graph.

What is the equation in factored form of the function graphed?

Which is a possible equation in factored form of the function in the graph?

If the graph of a function crosses the x-axis, what does that mean about the multiplicity of that zero?

• Even

• Odd

• None

A polynomial function has zeros at -1,2, and 7 (all multiplicity of 1). Write a function rule that could represent this function.

What are the extrema of the graph?

• Max = (0,-4)

  Min = (-1.5,0) and (1.5, 0)

• Max = (0,1.5) and (0, -1.5)

  Min = (-4,0)

• Max = (-1.5,0) and (1.5, 0)

  Min = (0,-4)

• Max = (-4,0)

  Min =(0,1.5) and (0, -1.5)

Based on the end behavior of the polynomial, what is the degree of the polynomial?

• a negative real number

• a positive real number

• an odd real number

• an even real number

Based on the end behavior of the polynomial, what best describes the leading coefficient?

• a negative real number

•  a positive real number

• an even real number

• an odd real number

If the graph of a function is tangent to the x-axis, what does that mean about the multiplicity of that zero?

• Even

• Odd

• None
