I need solve this question

Given that lim f(x) = 4 lim g(x) = -4 lim h(x) = 0, x - 3 x - 3 x - 3 find each limit, if it exists. (If an answer does not exist, enter DNE.) (a) lim [f(x) + 2g(x)] x - 3 (b) lim [g( x )13 (c) lim f(x) x - 3 2f(x) (d) lim x - 3 g(X) (e) lim g(x) x - 3 h(x) (f) lim g(x)h(x) x - 3 f(x)
