OpenStudy (darkbluechocobo):
f(x)= 6-x^2 and g(x)= sqrt(6 - x) f(g(x)) = 6-(sqrt(6 - x))^2 = 6 - (6 - x) = x g(f(x) = sqrt(6 - (6-x^2)) = sqrt (x^2)
OpenStudy (darkbluechocobo):
Not inverses because f is not 1 to 1. Make a domain restriction for f and make it one to one. f(x)= 6-x^2 for x >= 0 Since you are using the positive sqrt for the inverse.
