f(x) = 2x + 3 and g(x) = x^2 − 1.

fog(x)= 2(x^2-1)+3

gof(x) = 2x^2+1

gof (x) dosent equal to fog(x)

f(x) = x^2 − 1 and g(x) = 2x + 3.

fog ( x) = x(2x+3)^2-1

gof(x)= 4x^2+12x+8

gof (x) dosent equal to fog(x)

are thses right with proper working ?

if not can some1 show me the answear and the proper working

cheers
