Question

for the indicated functions f and g, find the functions f°g and g°f and find their domains

 

f(x) = √¯¯x¯¯; g(x) = x - 4

Answer 1

the first composite function is f of g(x)

 

if f of x is √x, then what is f of g(x) GIVEN g(x) = x-4

 

what this means is instead of doing the square root on x, you do it on x-4.
