Answer:

Hi,

All answers are good!

Explanation:

I suppose between 2x and the hole is the sign multiply

$f(x)=8x\\g(x)=2x*a\\(fog)(x)=f(g(x))=f(2x*a)=8*(2x*a)=16x*a\\$

Answer A:

$16x*a=16x+8=16x*(1+(1)/(2x) )\\\\a=1+(1)/(2x)\\$

Answer B:

$16x*a=16x+1=16x*(1+(1)/(16x) )\\\\a=1+(1)/(16x)\\$

Answer C:

$16x*a=16x^2+8x=16x*(x+(1)/(2) )\\\\a=x+(1)/(2)\\$

Answer D:

$16x*a=10x+1=16x*((10)/(16) +(1)/(16x) )\\\\a=(10)/(16) +(1)/(16x) \\$
