We can graph it using Desmos's calculator, here .

It crosses the y-axis at (0, -3) , so the y-intercept is -3 .

It crosses the x-axis at (1, 0) , so the x-intercept is 1 .

Its degree is 3 , so it can't have more than 2 turning points.

So we know that there's not another x-intercept way out that we can't see.
