Reflect

2016-09-20 14:13:35 UTC

We all say that the first one it flip upward or downward.

Reflect

Same figure but is flipped over axis.

Reflection

Equation:
Y=-1(x)^2
It's like a mirror
Flipping the original

Depended on what "a" is. An example of a reflection would be f(x)=x^2 to f(x)=-x^2. The "a" is something you can use to find the axis of symmetry.

Jumping Jacks like the arm legs, they get narrow as they go up

Vertical Stretch

18slor2666 — 2016-09-20 14:15:24 UTC

The higher the number, the more stretched out it is.

Vertical Compression

2016-09-20 14:17:09 UTC

The smaller "a" is the more compressed the graph. an example would be f(x)=.9x^2. If you graph this you will see that it flattens.

A rubber band

Reflection

2016-09-20 14:17:54 UTC

The slope is the opposite of the original slope or is negative

Vertical stretch

2016-09-20 14:18:36 UTC

It stretches wider from the parabola.

If you have negative axis symmetry the transition go left and if you have positive axis symmetry transition go right

Vertical Compression

2016-09-20 14:19:34 UTC

The smaller "a" is the more the parabola will compress. An example would be f(x)=(.05)x^2.

Vertical Stretch

18xlee3212 — 2016-09-20 14:19:48 UTC

The parabola gets pulled up or down ward
Equation:
y=-10(x)^2

Vertical

2016-09-20 14:20:00 UTC

It gets longer and thinner

Reflection

2016-09-20 14:20:44 UTC

The two halves of a parabola: Reflection is always across the x-axis, it's based on the axis of symmetry x=a number

Horizontal Translation

2016-09-20 14:21:29 UTC

The parabola will only move left or right on the x-axis.

y=0+5

Vertical Compress

2016-09-20 14:21:57 UTC

It compress the line closer to the x-axis.

Vertical Stretch

2016-09-20 14:22:15 UTC

Vertical stretch is the parabola getting skinnier because of a>1 or a<-1

Vertical Compression

18xlee3212 — 2016-09-20 14:22:26 UTC

Equation:
y=-0.1(X)^2

The parabola gets bigger and wider

Vertical tra

Vertical translation

2016-09-20 14:22:34 UTC

the Parabola will only move up or down on the y- axis.

Vertical Compression

2016-09-20 14:22:47 UTC

Vertical compression is when the parabola is getting wider because of a being >0 and <1, <0 or >-1.

positive y-intercept going up, negative y-intercept going down

2016-09-20 14:23:18 UTC

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

Horizontal Translation

2016-09-20 14:24:07 UTC

Parabola will only move left to right on the X-Axis

18xlee3212 — 2016-09-20 14:24:16 UTC

moving the parabola right and left horizontal only which mean the x-axis.
