Determine whether each pair of functions are inverse functions. f(x)=3x-1 f(x)=(1)/(4)x+5 f(x)=(1)/(2)x-10 g(x)=(1)/(3)x+(1)/(3) g(x)=4x … WebOct 28, 2024 · f (x) and g (x) are inverse functions because: f (g (x)) = x and g (f (x)) = x Explanation: Two functions f (x) and g (x) are inverses if g (f (x)) = x and f (g (x)) = x. So, f (x) and g (x) are equal to: Then, to find g (f (x)), we need to replace x by f (x) on the equation of g (x), so we get:
