What do "zeros" represent?

• something a polynomial can not be.

• the place that the polynomial crosses the x axis/ the x value that makes the whole equation equal to zero

• the place that the polynomial crosses the y axis/ the y value where x=0

• the number zero

What are the zeros of the polynomial function?
y = x(x - 6)(x + 5)

• 0, 6, -5
• 6, -5
• 0, -6, 5
• 1, -6, 5

For each function, determine the real zeros and state the multiplicity of any repeated zeros.

• {0 mult. 3}

• {0, 3, 1}

• {0, −2, −1}

• {−2, 3, 1}
