Question

What is the equation of the polynomial function shown on the graph?

Cubic polynomial function coming up from the left through the point negative two comma zero and turning at the point at approximately negative one comma eight and going down through the point zero comma six and through the point one comma zero and then turning at the point at approximately two comma negative four and going up through the point three comma zero and continuing towards infinity

y = –2x(x + 1)(x + 3)
y = (x + 2)(x − 1)(x − 3)
y = (x + 2)(x + 1)( x − 3 )
y = (x − 2)(x − 1)(x − 3)
