Question

Given the parent functions f(x) = log10 x and g(x) = 3x − 1, what is f(x) • g(x)?

f(x) • g(x) = log10 (3x − 1)x
f(x) • g(x) = log10 x3x − 1
f(x) • g(x) = 3x log10 x + log10 x
f(x) • g(x) = log10 x − 3x log10 x

Answer 1

that is C i belive

Answer 2

i thought it was A

Answer 3

\[\large\rm \color{royalblue}{f=(\log x)} \qquad\qquad\qquad \color{orangered}{g=(3x-1)}\]Then,\[\large\rm \color{royalblue}{f}\cdot\color{orangered}{g}\quad=\quad \color{royalblue}{(\log x)}\cdot\color{orangered}{(3x-1)}\]

Answer 4

put a times sign between them

Answer 5

Distribute the log x to each term.
