To do this I find the value of the first function at x = 2  5 = 3. that is I look at the value of the first function 5 units to the left of x = 2. Once I find the value of the first function at x = 3 I multiply this number by 4 to get the value of the second function at x = 2. So look at the points you just identified on the two graphs. If you are at the point on the first graph then the corresponding point on the second graph is 5 units to the right and its yvalue is 4 times the yvalue of the point on the first graph. So, for example if (2 3) is on the first graph then the corresponding point on the second graph has xcoordinate 2 + 5 = 7 and ycoordinate 4 3 = 12. I hope this helps,
