2.2E Graphing and Analyzing Higher-Degree Polynomials

Which of the following could be the equation of this graph in factored form? (Assume the x-axis is scaled by ones and the y-axis is not.)

• 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)
