Advanced Math practice question
A quantity is modeled by a function that increases by the same FACTOR over every interval of equal length. Which kind of function has this property?
- A. ExponentialCorrect
- B. Linear
- C. Quadratic
- D. Absolute value
Answer: A. Exponential
Multiplying by a fixed factor per step is exactly exponential growth; linear functions instead add a fixed amount per step.
Why the other answers are wrong
- B. Linear
- Linear functions grow by equal differences, not equal factors.
- C. Quadratic
- A quadratic's growth factor changes from interval to interval.
- D. Absolute value
- Absolute-value functions are two linear pieces — equal differences, not factors.
