Find the domain of the function (f/g) (x) where f (x) = √x+1, g (x) = √x-9

4x + 9. Given f (x) = 2x + 3 and g (x) = - x2 + 5, find (g o g) (x). (g o g) (x) = g (g (x)) ... Given f (x) = sqrt (x) and g (x) = x - 2, find the domains of (f o g) (x) and (g o f) (x). Since f (x) involves a square root, the inputs have to be non-negative ... Given h (x) = (x + 1) 2 + 2 (x + 1) - 3, determine two functions f (x) and g (x
