Question

Given the parent functions f(x) = log3 (5x − 5) and g(x) = log3 (x − 1), what is f(x) − g(x)?

f(x) − g(x) = log3 (4x − 4)

f(x) − g(x) = log3 (4x − 6)

f(x) − g(x) = log3 5

f(x) − g(x) = = log3 one fifth

Answer 1

http://www.chilimath.com/algebra/advanced/log/images/rules%20of%20exponents.gif <--- notice the 2nd rule listed there,

so what do you think that gives us for

\(\bf f(x) = log_3 (5x - 5) \qquad g(x) = log_3 (x - 1)
\\ \quad \\
f(x)-g(x)=log_3 (5x - 5)-log_3 (x - 1)\implies ?\)

Answer 2

would it be B f(x)-g(x)=log3(4x-6) @jdoe0001

Answer 3

hmm what did you get for \(\bf log_3 (5x - 5)-log_3 (x - 1)\quad ?\)
