Polynomials Zeros, Factors, and Multiplicities

What is the factored form of a function if it has zeros of 2, 3 and -1?

• (x-2)(x-3)(x+1)
• (x-1)(x-2)(x-3)
• (x-1)(x+2)(x+3)
• (x+1)(x+2)(x+3)

The degree of the polynomial determines the number of zeros.

• True
• False

True or False:  If (7x + 4) is a factor of some polynomial function f, then 4/7  is a zero of the function. 

• True
• False

What is another way to say "where a function crosses the x-axis"?

What is the degree?

• Even
• Odd

Match the equation to the graph.

• y=-(x+1)(x-2)(x-4)
• y=(x+1)²(x-3)(x-1)³
• y = 3x³ – 2x + 1
• y=(x+1)³(x-3)(x-1)²
