The function f(x)=log2x is transformed 4 units down and vertically compressed by a factor of 0.2 to become g(x). Which function represents the transformation g(x)?

g(x)=1/5log2(x)−4
g(x)=−4log2(15x)
g(x)=−4log2(x+1/5)
g(x)=1/5log2(x−4)

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
