Write the equation of the graph shown below in factored form.

the graph starts at the bottom left and continues up through the x axis at negative three to a maximum around y equals twenty and goes back down through the x axis at one to a minimum around y equals negative twelve point five and back up through the x axis at four

f(x) = (x − 3)(x + 1)(x + 4)
f(x) = (x + 3)(x − 1)(x − 4)
f(x) = (x + 3)(x + 1)(x + 4)
f(x) = (x − 3)(x − 1)(x − 4)
