Question

x -13 | -9 -5 -1 27 30 2722 N. linear 0. nonlinear

Answer 1

We have a table with x and y values, and want to know if the function is linear or nonlinear.

In this case we can see that the value y=27 repeat for x=-13 and x=-5, so this function could not be linear, because two values of x have the same y value.
