Answer: Choice D. g(x) = 3|x-3| - 6</h3>
======================================================
Explanation:
Points are of the form (x,y), where y = f(x) since y and f(x) are outputs.
When we vertically stretch by a factor of 3, we are making the function curve 3 times more stretched out along the vertical y axis. So a general point (x,y) becomes (x,3y). Whatever the y coordinate is, we multiply by 3 to get its stretched out counterpart.
Eg: (0,-2) on f(x) moves to (0,-6) which is on g(x)
-------------
Since y = f(x), and we're multiplying y by 3, we can say
f(x) = |x-3| - 2
3*f(x) = 3*( |x-3| - 2 )
3*f(x) = 3|x-3| + 3(-2)
3*f(x) = 3|x-3| - 6
g(x) = 3|x-3| - 6
2log5(12) - log5(8) - 2log5(3)
= log5(12²) - [log5(8) + 2log5(3)]
= log5(144) - log5(8*3²)
= log5(144/72)
= log5(2)
= ln2/ln5
≈ 0.43068
