Given the table
The change in x is
The change in y is
Since for the same change in x, the change in y is different, given table represents nonlinear function.
D, Because there is no correlation between the x and y points
The table shows linear function.
1. From x = 1 to x = 2 (change in x is +1), y changes from 6 to 8 (that is +2)
2. From x = 2 to x = 3 (change in x is +1), y changes from 8 to 10 (that is +2)
3. From x = 3 to x = 4 (change in x is +1), y changes from 10 to 12 (that is +2)
4. From x = 4 to x = 5 (change in x is +1), y changes from 12 to 14 (that is +2)
This means for constant change in x (+1) there is a constant change in y (+2), so the function represented by given table is linear.
A?? because I think it's not linear because it's not proportional
A because when the points are plotted they make a straight line.
