Best ResponseYou've already chosen the best response.3Well we start at 30 and go to 22....so thats 1 root and we go from 34 to 130 ....make that 2 roots And finally we go from that 130 to 222...so I count 3 roots

Best ResponseYou've already chosen the best response.0So just to make sure I understand this, Say we have x=1,2,3,4,5,6 p(x)= 55, 100, 200, 225, 300, 325 So this would have; 55 to 100, 1 root 200 to 225, 2 roots 225 to 300, 3 roots 300 to 325, 4 roots ?
