You can put this solution on YOUR website!
the zeros of the function +%28x-3%29%28x%2B3%29%28x-4%29+=0 are:
+%28x-3%29=0=>+x=3
+%28x%2B3%29=0=>+x=-3
+%28x-4%29=0=>+x=4
function is:
f%28x%29=+%28x-3%29%28x%2B3%29%28x-4%29+
f%28x%29=+%28x%5E2-9%29%28x-4%29+
f%28x%29=+x%5E3-9x-4x%5E2%2B36+
f%28x%29=+x%5E3-4x%5E2-9x%2B36+
you have three points already, find some more, plot them and draw a graph
x|f%28x%29=y
4|0
-3|0
3|0
1|24...f%281%29=+1%5E3-4%2A1%5E2-9%2A1%2B36=+24
2|10...f%282%29=+2%5E3-4%2A2%5E2-9%2A2%2B36=+10
3|0...f%283%29=+3%5E3-4%2A3%5E2-9%2A3%2B36=+0
