Tell whether each function is linear or non-linear.

Function A line1 Function B

x 0 1 2 3

y 0 1 8 27

y = –x + 5


Function A is non-linear and Function B is non-linear.


Function A is linear and Function B is non-linear.

Answer:

Function A is non-linear and Function B is linear.

Step-by-step explanation:

Linear function:

Has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

In a linear function, when x changes by 1, y will always changes by the same amount.

Function A:

When x changes by 1, y can change by various amounts. So function A is non-linear.

Function B:

y = -x + 5

In the format of a linear function, so linear
