WebGiven two functions f ( x) and g ( x), test whether the functions are inverses of each other. Determine whether f ( g ( x)) = x or g ( f ( x)) = x. If either statement is true, then both are … WebAre f (x) and g (x) are inverse to each other ? Solution : To check whether f (x) and g (x) are inverse to each other, find f o g and g o f. f o g : f o g = f [g (x)] = f [x + 3] = x + 3 - 3 = x ---- (1) g o f : g o f = g [f (x)] = g [x - 3] = x - 3 + 3 = x ---- (2) From (1) and (2), f o g = g o f = x So, f(x) and g (x) are inverse to each other.
