Which of the following functions has a graph in the xy-plane that passes through both (1, 5) and (2, 25)?
- A. y = 5ˣCorrect
- B. y = 5x
- C. y = x + 4
- D. y = x² + 4
Answer: A. y = 5ˣ
5¹ = 5 and 5² = 25.
Why the other answers are wrong
- B. y = 5x
- 5(2) = 10, not 25.
- C. y = x + 4
- 2 + 4 = 6, not 25.
- D. y = x² + 4
- 2² + 4 = 8, not 25.
