its in vertex form
-3 means is open down or looks like this ∩
the vertex is (-2, 7) - opposite of the number in brackets and the constant 7
so it increases from - ∞ to -2 and decrease after
g) - ∞ to -2
h) -2 to ∞
i) at the ends it points down to - ∞
j) multiply is out at put it in ax² +bx + c standard form, its in vertex
