Here, f(x+4)= 5x + 1 Put, x = x - 4, we get f(x - 4 +4)= 5(x - 4) + 1 or, f(x) = 5x - 19. Now, fof(x) = f(5x - 19) = 5(5x - 19) - 19 = 25x - 114. Again, g(x) = 2x - 3. or, y = 2x - 3 For inverse function, x = 2y - .....

We know, 70 = 20 + 50 Operating by tan we get, tan70= tan(20+50) Using formula of tan(A+B),we get
or, tan70= (tan50 + tan20)/(1-tan50tan20)
or, tan70- tan70tan50tan20= tan 50 + tan20
or, tan70 = tan50 + tan20 + .....
