Jackson, Aria, and Harper are studying the population growth of a certain species of bacteria. They notice that the population growth does not seem to be linear, but rather, it seems to be growing at an increasing rate. Which concept could they use to model this type of growth?

• They could use exponential regression, which models the relationship between equal-length input intervals and proportional output intervals.

• They could use exponential regression, but it is only applicable to discrete data.

• They could use exponential regression, which models the relationship between equal-length input intervals and linear differences in outputs.

• They could use exponential regression, which is used to model linear relationships between variables.

Is the table linear, exponential, or quadratic?

• Linear

• Exponential

• Quadratic

• none of these
