f(x) = log3 (x) is reflected across the y-axis, then horizontally shrunk by a factor of 3/7 then moved down 9 units, what is the new equation for g(x) ?

Question

A) g(x) = - log3 (7/3 * x) - 9

B)g(x) = log3 (- 7/3 * x) - 9

C) g(x) = log3 (- 3/7 * x) - 9

D) g(x) = log3 (- 7/3 * x) + 9

Answers^

Answer 1

reflection over the y axis leads to

y = -log3(x)

down 9

y = -log3(x) -9

only A) has those two signs correct, without considering the compression
