Plz help me I don't know this ​

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

In a graph with several intervals o data how does a constant interval appear? what type of scenario produces a constant interval?

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4
