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)

• x = -3, x = 5

• x = -3, x = 0, x = 5

• x = -3, x = 2, x = 5

• x = 0

What are the zeroes of this graph?

• x = -2, x = 1, x = 4

• x = -4, x = 0, x = 1, x = 2,

• x = -2, x = -1, x = 0, x = 4

• x = -4, x = -1, x = 2

What is the equation of this graph in factored form?

• (x - 1)(x + 3)²

• (x - 1)²(x + 3)

• (x + 1)²(x - 3)

• (x + 1)(x - 3)²
