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

1 answer:

6 0

F(x) = ㏒₃(5x - 5)
g(x) = ㏒₃(x - 1)

f(x) - g(x) = ㏒₃(5x - 5) + ㏒₃(x - 1)
f(x) - g(x) = ㏒₃(⁵ˣ⁻⁵/ₓ₋₁)
f(x) - g(x) = ㏒₃(⁵⁽ˣ⁾⁻⁵⁽¹⁾/ₓ₋₁)
f(x) - g(x) = ㏒₃(⁵⁽ˣ⁻¹⁾/ₓ₋₁)
f(x) - g(x) = ㏒₃(5)

sineoko [7]

I think the answer would be A because 5% ×100=0.05 , and in the question they have been telling us that it decreased by 5 from the last week so the equation would be g of the last week - 0.05
