Question

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

Answer 1

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
