+128475 Note that at x = -1, y = 0 so x = -1 is a root
And note that when x = 0, y =3 and when x = 1, y = -1....so....the graph must cross the x axis between x = 0 and x = 1.....so...we have another root on this interval
Finally.....at x = 1, y =-1 and at x = 2, y =4 ...so.....the graph must again cross the x axis ......so...we have another root
Lastly at x = x, y= 4 and at x =3, y = -1...so....the graph crosses the x axis one last time...so....we have one more root
So.... since the function crosses the x axis 4 times....we have 4 roots...so....the degree is 4
We have one negative zero at x = -1
And the other three roots are positive
