HELP PLEASE!
Given the parent functions f(x) = log10 x and g(x) = 5x − 2, what is f(x) • g(x)?

f(x) • g(x) = log10 x5x − 2

f(x) • g(x) = log10 (5x − 2)x

f(x) • g(x) = 5x log10 x + 2 log10 x

f(x) • g(x) = 2 log10 x − 5x log10 x

solomonzelman · Answer

when you say " f(x) • g(x)" it is same as saying

[    log10 x    ] •  [  5x − 2   ]

Okay but I don't know how to solve that

solomonzelman · Answer

just multiply them together.

anonymous · Answer

so multiply 10 and 5

solomonzelman · Answer

10, as far as I can see it is the base of the log. (this is my best interpretation of the problem)
