If the function h(x) Is defined as vertical stretch by a factor of 2 followed by a reflection in the X-axis of the function F(x) then h(x)=

A)2f(-x)
B) 1/2 f(x)
C) -1/2 f(x)
D) -2f(x)

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

he kicked it up? is this the answer ?
