Graph Polynomials

What does multiplicity of a zero mean?

• Look at the number of terms
• How many times the zero repeats
• Find the sum of all the coefficients
• Ratio your x and y

The largest exponent determines the degree of the polynomial.

• True
• False

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

• x-intercept
• zero
• root
• all of these.

What are the zeros of the polynomial and state their multiplicity at each.
y = (x - 5)(x + 2)²

• x = 5 multi 1,  x = 2 multi 2
• x = -5 multi 2, x = -2 multi 1
• x = 5 multi 1, x = -2 multi 2
• x = 5 multi 2, x = -2 multi 1

What is the equation in factored form of this graph?

• f(x) = (x-4)(x-1)²(x+2)(x+4)
• f(x) = (x-4)(x+1)²(x+2)(x+4)
• f(x) = (x-4)(x-1)²(x-2)(x+4)
• f(x) = (x+4)(x+1)²(x-2)(x-4)
