• None

What is true about the x-intercepts of an odd degree polynomial?

• It always has two x-intercepts

• It never crosses the x-axis

• It can have zero x-intercepts

• It must have at least one x-intercept

What defines an even function?

What is the first step in dividing polynomials using long division?

• Subtract the divisor from the dividend

• Add the divisor to the dividend

• Multiply the divisor by the dividend

• Divide the highest degree term of the dividend by the highest degree term of the divisor
