Which of the following is the correct equation for the function graphed?

Which of the following could be the equation for the polynomial shown?

• f(x)=(x-1)(2x+1)(x-3)

• f(x)=(x-1)(2x+1)²(x-3)

• f(x)=(x-1)²(2x+1)(x-3)

• f(x)=(x-1)(2x+1)(x-3)²

• None of these would match the graph

Remember to look at your roots, multiplicity, and end behavior!! Use your notes!

• y = ^_(x + 2)(x - 1)²

• y = -(x - 2)(x + 1)²

• y = (x - 2)(x + 1)²

• y = -x³
