What is the common name for the growth rate function N?

constant

logarithmic

linear

quadratic

cubic

exponential

factorial

Linear.

Explanation:

The common name for the growth rate function N is linear. N growth rate is directly proportional to the input. So it grows linearly. It does not grow rapidly like other growth functions like quadratic, exponential and cubical.

Constant growth does not grow over time it stays as it is.

Hence the answer to this question is linear.
