Hi
y-intercept(when x = 0) is -36 
x-intercepts: -3,-2,2,3 can be found with Synthetic Division noticing x=2 is one root
2  -1	0	13	0	-36
	-2	-4	18	36
   -1	-2	9	18	0
(x-2)(-x^3 -2x^2 +9x + 18)  Note: x = -2 root for -x^3 -2x^2 +9x + 18
-2  -1	-2	9	18	
	2	0	-18	
   -1	0	9	0
(x-2)(x+2)(-x^2 + 9)
((x-2)(x+2)(x-3)(x+3)
