Question

Find (f ○ g)¯¹(x) and (g¯¹ ○ f^-1)(x) if f(x) = 5x and g(x) = x - 7.

Accepted Answer

(f ○ g)^-1(x) = (x + 35)/5, (g^-1 ○ f^-1)(x) = x/5 + 7

Answer

(f ○ g)^-1(x) = x + 28, (g^-1 ○ f^-1)(x) = x/3 + 4

Answer

(f ○ g)^-1(x) = 3x + 5, (g^-1 ○ f^-1)(x) = (x + 5)/2

Answer

(f ○ g)^-1(x) = x/7 + 2, (g^-1 ○ f^-1)(x) = (x + 1)/3

Find (f ○ g)¯¹(x) and (g¯¹ ○ f-1)(x) if f(x) = 5x and g(x) = x - 7.
