What is a₁₂?
- A. 62 ✓
- B. 67
- C. 60
- D. 57
Correct answer: A. A₁₂ = 7 + 5(12 − 1) = 7 + 55 = 62.
What is g₅?
- A. 48
- B. 96 ✓
- C. 192
- D. 13
Correct answer: B. G₅ = 3(2)⁵ = 3 × 32 = 96.
Which best describes f?
- A. Exponential with base 3.
- B. Exponential, because the outputs increase.
- C. Linear, because the outputs increase by 3 each time x increases by 1. ✓
- D. Quadratic, because the outputs are positive.
Correct answer: C. A constant difference over equal intervals means linear: f(x) = 10 + 3x.
What is f(2)?
- A. 36 ✓
- B. 10
- C. 144
- D. 24
Correct answer: A. 3² = 9, and 4 × 9 = 36.
Which statement is true?
- A. f is linear with slope 0.5.
- B. f shows exponential decay with initial value 6. ✓
- C. f shows exponential decay with initial value 0.5.
- D. f shows exponential growth with initial value 6.
Correct answer: B. F(0) = 6 and the base 0.5 is between 0 and 1.
