A). y=4x-8, D(y)=(-∞;∞)
[x - любое число]
б). y=x²-5x+1, D(y)=(-∞;∞)
[x- любое число]
в). y=2x/(5-x), 5-x≠0, x=5
D(y)(-∞;5)U(5;∞)
[x- любое число, кроме 5]
г). y=3/((x-4)(x+1)), (x-4)*(x+1)≠0, x≠4, x≠-1
D(y)=(-∞;-1)U(-1;4)U(4;∞)
[х- любое, кроме -1; 4]
д). y=1/(x²+1), x²+1≠0 верно при любых значениях х
D(y)(-∞;∞)
е). y=√(x-5) , x-5≥0, x≥5
D(y)=[5;∞)
