Answer 2

@jdoe0001 whats that

Answer 3

a parabola is vertex form... notice the vertex coordinates

Answer 4

? so whats the answere

Answer 5

well.. look at yours \(\bf y = a(x-{\color{brown}{ h}})^2{\color{olive}{ +k}}\quad vertex\ ({\color{brown}{ h}},\color{olive}{ k})\quad y = –3(x + 8)^2 + 2\)
