Answer: A) stretched vertically by 2 and shifted up 6 units
Step-by-step explanation:
y = A log(Bx - C) + D where
- A = vertical stretch by a factor of A
- B = horizontal shrink by a factor of 1/B
- C = horizontal shift C units (positive = right, negative = left)
- D = vertical shift D units (positive = up, negative = down)
Given: f(x) = log x
g(x) = 2 log x + 6
→ A = 2 vertical stretch by a factor of 2
→ D = +6 vertical shift UP 6 units
