Question

use the information provided to write the standard form equation of each parabola.

1. y = 2(x + 7)^2 - 6

Answer 1

In this one we're going backwards, what is vertex in this?

Answer 2

is it this formula -b/2a ?

Answer 3

No remember what i showed you on the last one, vertex form, what is the vertex just by looking at it (h,k)

Answer 4

ohhh

Answer 5

(-7, -6)

Answer 6

Right!

Answer 7

Ok was checking if you understood it, you just need to foil to put it in standard form y =ax^2+bx+c

Answer 8

\[y=2(x+7)^2-6 \]
\[(x+7)^2 = (x+7)(x+7)\]

Answer 9

@Astrophysics wait i'm confused, what did you do there?

Answer 10

You just have to foil out the (x+7)^2 the exponent 2 means there's two of them

Answer 11

multiply...
