How do you find the answers to g, h, i, and j?

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

i dont know sorry
