Vertex Form

200620581 — 2017-03-24 21:11:51 UTC

y = a (x-h)^2 + k

h < 0 shifts left
h > 0 shifts right

a < 0 concave down
aa > 0 concave up/ vertical stretch/steeper
a< 1

k < 0 shift down
k > 0 shift down

Standard Form

y = ax^2 +bx + c

The a is the same as in vertex form.

The c is the y - intercept.

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

Unit Question

200620581 — 2017-03-30 21:31:59 UTC

How Long Will The Rocket Take To Reach The Top?
How High Will The Rocket Go?
How Long Will The Rocket Be In The Air?
These Questions Are easy to Answer Using This Equation:
h(t)= 160 +92t- 16t

h(t) is the rockets height

160 is the height of the tower

92 (t) is the feet per second

16 (t)^2 is the force of gravity

Lets Plug In A Number

200620581 — 2017-03-31 21:44:44 UTC

t=3

h(3) =160 +92(3) - 16 (3)^2

h=292
