Solution: f(x)=ax−3 and g(x)=xb+c, x∈R. f(g(x))=a(xb+c)−3=axb+ac−3 ∴(f(g(x)))−1=x+3−aca1b==x−7213 ∴b=3; a=2; c=5f(x)=2x-3, g(x)=x3+5 (fog) (ac) + (gof) (b)=(fog) (10) + (gof) (3) =f(1005)+g(3) =2007+32=2039 Related content Matrices and Determinants_mathematics Critical Points Solved Examples Type of relations_mathematics
