Advanced Math practice question
Which of the following functions has the greatest value when x = 3?
- A. y = 2ˣCorrect
- B. y = 2x
- C. y = x + 2
- D. y = x/2
Answer: A. y = 2ˣ
2³ = 8, while the others give 6, 5 and 1.5.
Why the other answers are wrong
- B. y = 2x
- 2(3) = 6.
- C. y = x + 2
- 3 + 2 = 5.
- D. y = x/2
- 3/2 = 1.5.
