Advanced MathMediumGraph of a shifted exponential
Advanced Math practice question
In the xy-plane, the graph of y = 2ˣ − 1 passes through which of the following points?
- A. (0, 0)Correct
- B. (0, 1)
- C. (1, 2)
- D. (2, 4)
Answer: A. (0, 0)
2⁰ − 1 = 0.
Why the other answers are wrong
- B. (0, 1)
- (0, 1) lies on y = 2ˣ, before the shift.
- C. (1, 2)
- (1, 2) lies on y = 2ˣ.
- D. (2, 4)
- (2, 4) lies on y = 2ˣ.
