Alg2 U4 Directional Lock

There are rumors one of the antidote locks has been left in a warehouse...

room 1

Vertex (2, 3) Point (0, 7)

y = (x - 2)2 + 3y = (x + 2)2 + 3 y = (x - 2)2 - 3 y = (x + 2)2 - 3

You enter into a long corridor... which way should you go?

room 2

f(x) = (x + 2)(x + 4) f(x) = 1/5(x - 2)(x - 4) f(x) = (x - 2)(x - 4) f(x) = 1/5(x + 2)(x + 4)

X-intercepts: (2, 0) and (4, 0); Point (1, 3)

It's really dark in here, did you hear that???

Vertex (-2,1) Point (1,28)

room 3

y = -27(x-2)2 + 1 y = 3(x + 2)2 + 1 y = 3(x - 2)2 + 1 y = 27(x+2)2 + 1

Move quickly! Someone or someTHING is in here!

room 4

f(x) = 2(x - 1)(x - 7) f(x) = 3(x - 1)(x + 7) f(x) = 3(x - 1)(x - 7) f(x) = 2(x + 1)(x - 7)

X-intercepts: (-1, 0) and (7, 0); Point (5, -24)

Daylight! This looks promising!

room 5

y = 4(x + 1)2 - 5 y = (x - 1)2 - 5 y = (x + 1)2 - 5 y = 4(x - 1)2 + 5

Vertex (-1, -5) Point (1, -1)

Last stop- the attic! Let's hope we don't have to come back here...
