# Let f, g : R <spa

Formula:-

(i)Let f : AB and g : BC be two functions.

Then, the composition of f and g, denoted by g o f, is defined as the function g o f : AC

given by g o f (x) = g (f (x))

Given:-

(i)f, g : R R

(ii)f(x) = 2x + 1

(ii)g(x) = x2 – 2 for all x ϵ R

gof(x)=g(f(x))

gof(x)=g(2x+1)

gof(x)=(2x+1)2-2

gof(x)=4x2+4x-1
