The y intercept is (0,-210).
The x intercepts are best found by using a graph. If their is an integral solution, look for the factors of 210.
The best way to find out the answer to your question is just to graph the function. That graph can be found here.
It looks like the x intercepts are 5,6,7
f(x) = (x - 5)(x - 6)(x - 7) is the way this graph would would be factored.
