Question

Identify which of the following functions decreases as x increases.:

f(x)=log_4/5^x or g(x)=log_3^x

hero · Answer

Can you write that out? It is not clear what the bases are.

anonymous · Answer

okay
$$f(x)=\log _{4/5^{X}}$$ 
or
$$g(x)= \log _{3^{X}}$$

anonymous · Answer

not sure how to do the fraction thing on the equation function on here but the 4/5 is a fraction on the first one.

hero · Answer

Hint: The one of the bases is a whole number; the other base is a fraction.

anonymous · Answer

so the answer is the second equation because it's not a fraction? lol just guessing. i think i had a question like this before.

hero · Answer

Actually, they want the function that DECREASES as x increases

hero · Answer

logs of fractions produce negatives

anonymous · Answer

oh okay. so since negatives are going lower, the answer would be the first one?
