Question

Quizplus · Accepted Answer

A function is linear if it has a constant rate of change, meaning that the change in the output value is proportional to the change in the input value. In function C, the term 5YZ makes it non-linear because the rate of change of Y is dependent on Z as well, which violates the condition of constant rate of change. The other options have a constant rate of change and are linear functions. Additionally, option D is a constant function, which is also considered linear.
