I followed all the steps and when i plug in my function on desmos to check it up, it shows me a different graph. The graph I was given has the following zeros(x-int)--> -1, 1, 2. and y-int--> (0, -4) . After solving for A using (0, -4) I got the following polynomial--> f(x)=-2(x+1)(x-1)(x-2) and the graph is different from the one i was given. Any ideas

If the y-intercept is (0, 0) does a also equal 0?

What would be the degree of this polynomial?
