Question

Given the parent functions f(x) = log2 (3x − 9) and g(x) = log2 (x − 3), what is f(x) − g(x)?

f(x) − g(x) = log2 (2x − 6)

f(x) − g(x) = log2 (2x − 12)

f(x) − g(x) = log2 one third

f(x) − g(x) = log2 3

Answer 1

Hmm, I'm not so sure about this one. I don't remember much about these types of functions from Algebra 1 Dx

Answer 2

this is Alg2

Answer 3

Im taking Geometry, so I am not at this level quite yet :c

Answer 4

lol its ok

Answer 5

f(x) − g(x) = log2 (2x − 6)

f(x) − g(x) = log2 (2x − 12)

f(x) − g(x) = log2 one third

f(x) − g(x) = log2 3

So my answer is D

Answer 6

f(x) = log2 (3x − 9) and g(x) = log2 (x − 3), what is f(x) − g(x)

f(x) − g(x) = log2 (3x − 9) -log2 (x − 3)
\[f(x)−g(x)=\log_2\frac{(3x−9)}{(x−3)}=\log_2 \frac{3(x−3)}{(x−3)} =\log_2 3\]


Thus
\[f(x) − g(x) = \log_2 3\] is the required answer
