If f(x) = x + 7 and g(x) = x - 7, x∈R, find ( fog) (7)
Given f(x) = x + 7 and g(x) = x - 7, x∈R fog(x) = f(g(x)) = g(x) + 7 = (x - 7) + 7 = x => (fog) (7)...

Let f : R→R be defined as f(x) =10x +7. Find the function g : R→R such that gof =fog =IR.
gof = fog = IR => fog = IR => fog(x) = I (x) =>f (g(x)) = x [I(x) = x being identity function] =>10 (g(x)) + 7 = x ...

Write fog, if f : R→R and g : R→R are given by f(x) = 8x^3 and g(x)=x^1/3.
fog (x) = f (g(x)) = f (x1/3 ) =8(x1/3 )3 =8x
