Answer: parasitism
Explanation: Because it's relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.
Simple problem my friend!
First we must replace X with -2,-1,0,1,2
then we plug in -2 in X. 8*-2 is -16 and adding 12 gives us a co ordinate of (-2,-4) now this is not enough so now we must do -1. 8*-1 is -8, + 12 gives us 4. so now our second co ordinate is (-1,4). i will do 1 more co ordinate and then you should be able to finish the problem by yourself :) we now plug in 0 to replace X. 8*0 is 0, easy and 0+12 is 12. so the third co ordinate is (0,12) when you have put all the dots on the graph be sure to draw a line through them and by the way, this is not a biology question lol, good luck!
