Write the equation of the graph shown below in factored form. a graph that starts at the top left and continues down through the x axis at one to a minimum around y equals negative zero point six and goes up to cross the x axis two to a maximum around y equals zero point two and and then goes back down to a touch the x axis at three and then goes back up to the top right.

f(x) = (x − 3)2(x + 2)(x − 1)
f(x) = (x + 3)2(x − 2)(x + 1)
f(x) = (x + 3)2(x + 2)(x + 1)
f(x) = (x − 3)2(x − 2)(x − 1)
