Question 1013979
.
Are the two functions inverses f(x)=-2x+12 and g(x)=-(x/2)+6 ?
-----------------------------------------------------------------


1.  (fog)(x) = {{{(-2)*(-(x/2)+6) + 12}}} = x - 12 + 12 = x.


2.  (gof)(x) = {{{-((-2x+12)/2) + 6}}} = x - 6 + 6 = x.


<U>Answer</U>. &nbsp;Yes, &nbsp;these two functions are inverse each other.
