Homework 1.4 (To verify the linear inverse by composition) State if the given functions are inverses. 1) f(x)=x+4 g(x)=x-4 fcgcx)) = (x-4)+4=x-4+4=x g(f(x)) = (x+4)-4=x+4-4=x Yes they are inverses 3) f(n)=3n-9 4 h(n)-2n-2 FF(ha) (2-2) = 3(n-2) 2) g(n)- 5n-20 8 Period s(n)= 20+ 8n 5 f(g(x)) = 5 (20+3)-20 4) g(x)=x-1 f(x)=-4x+8 9/4 = 60-6-9/1=-2494-64 HCFONDE 4-3n 2 5) g(n) = f(n) = -2n+4 3 3 6) f(x) = -2x+1 8(x)=-2x 1 2 5 8 7) g(x) = x+ f(x)=x-2 4 3 8) g(x) = x f(x) = x
