f(x)=2-x
+g%28x%29=sqrt%283%29-x
fog(x)= f(g(x))
=+f%28sqrt%283%29-x%29
= 2-%28sqrt%283%29-x%29
=2-sqrt%283%29%2Bx
we need to piut x=-1 to find out fog(-1)
fog(-1)= +2-sqrt%283%29%2B%28-1%29
= 1-sqrt%283%29

find the indicated function value, if it exists,
given f(x) = 2 - x and g(x) √3-x
(fg)(-1)
g%28x%29+=+sqrt%283+-+x%29

g%28-+1%29+=+sqrt%283+-+-+1%29

g%28-+1%29+=+sqrt%284%29_______g(- 1) = 2



f(x) = 2 - x

f(g(- 1)), or f(2) = 2 - 2, or highlight_green%280%29    

You can do the check!!
