Question

Grade 9 math
useing frist diff is this a linear relation yes or no show your work

Answer 1

not linear since all first differences are not equal

Explanation:

To find the first differences, subtract each y value from the next y value.

Use only y values.

here are the 4 first differences you need to calculate.

1 - 0 = 1

4 - 1 = 3

9 - 4 = 5

16 - 9 = 7

Now you place them in the appropriate column in the table.

x y first difference

0 0 1

1 1 3

2 4 5

3 9 7

4 16

If the first differences were all equal, the function would be a linear function.

In this case, the first differences are all different, 1, 3, 5, 7, so the function is not linear.
