I will give brainiest to whoever answers correctly !!

With #! i’ve tried to figure it out but i can’t.

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

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
