Advanced MathEasyDescribing a doubling table
Advanced Math practice question
The table shows values of a function g. x | g(x) 0 | 1 1 | 2 2 | 4 3 | 8 Which statement describes how g(x) changes each time x increases by 1?
- A. g(x) doubles.Correct
- B. g(x) increases by 1.
- C. g(x) increases by 2.
- D. g(x) halves.
Answer: A. g(x) doubles.
1 → 2 → 4 → 8: each value is twice the one before.
Why the other answers are wrong
- B. g(x) increases by 1.
- The increases are 1, 2, 4, not a constant 1.
- C. g(x) increases by 2.
- The increases are not constant.
- D. g(x) halves.
- The values grow, not shrink.
