Which of the following functions increases as x increases?
- A. y = 3ˣCorrect
- B. y = (1/3)ˣ
- C. y = 3
- D. y = −3x
Answer: A. y = 3ˣ
A base greater than 1 makes the function grow.
Why the other answers are wrong
- B. y = (1/3)ˣ
- A base between 0 and 1 makes the function shrink.
- C. y = 3
- A constant does not change.
- D. y = −3x
- A negative slope decreases.
