Answer 1

why is the first one false ? how you get it false ?

Answer 2

just bc. you check it for x=0 you get y=0 what is true than you see the graph and for x=-4 you get y=0 what than you check the graph is true too

so i believe that this graph is true

Answer 3

f(x)=3(x^2+4x+4-4)=3(x+2)^2-12
vertex is (-2,-12)
hence false

Answer 4

yes you are right bc, for x=-2 you get y=-12 so and not -8
