Question

Is the function linear or nonlinear?

Answer 1

the function is nonlinear, as the y-values do not go down at the same rate.

Answer 2

Answer:

Non-linear

Step-by-step explanation:

X      Y

7     20

8      11

9      4

When you go from 20 to 11, you subtract 9.

However, when you go from 11 to 4, you only subtract 7.  

Therefore, it is not linear.
