Question

Which statement best explains whether the table represents a linear or nonlinear function?

It is a linear function because there is a constant rate of change in both the input and output values.

It is a nonlinear function because there is a constant rate of change in both the input and output values.

It is a linear function because the input values are decreasing.

It is a nonlinear function because the input values are increasing.



Input
(x) Output
(y)
−2 7
−5 4
−8 1
−11 −2

Answer 1

The correct answer is:

It is a linear function because there is a constant rate of change in both the input and output values.

Explanation:

Given table is:

Input (x) Output (y)

−2 7

−5 4

−8 1

−11 −2

It can clearly be observed that the values for x and y are changing with the same rate.

In case of x, -3 is added to the previous input to get the next input.

Similarly, in case of y, the next output value is obtained by subtracting 3 from the previous value.

Hence,

The correct answer is:

It is a linear function because there is a constant rate of change in both the input and output values.
