linear transformation notes- is this right??

[Dreams_Of_Cheese]

it's a joke, can't you take it?

And here I am, thinking that jokes are supposed to be funny.

X is reversed, so y = (x+2)² will be a parabola shifted 2 units left, while y = (x-2)² will go to units right.

add for right
subtract for left

Lies.

I am not sure I understand your question. When you subtract from coordinates, the point moves more to the left or more towards the bottom depending on if you subtract from x or y respectively. When you add, it moves either to the right or to the top depending on if you're modifying x or y respectively. I probably misunderstood your question though.

sorry bro i take algebra 1, maybe next time.

this IS algebra 1 work lmao

[Electro]

this IS algebra 1 work lmao

we don't do it lol.

[.:FancyPants:.]

if the slope is positive then adding to Y (going up) makes you subtract from X (going left). in the same case, subtracting from Y (going down) makes you add to X (going right).
by going left/right/up/down i'm referring to the intercepts, of course.

if the slope is negative then instead of
Y up = X left and Y down = X right, it's
Y up = X right and Y down = X left.

I remember doing this in 8th, pre-algebra.

[Ninja Decoy]

I did this stuff in Algebra II a few weeks ago, and it confused me for a bit. When adding inside the parentheses, you move to the left. When subtracting in the parentheses, you move right. Both of these only apply to the X axis.
so, (x-1) means you move 1 unit to the right, and (x+2) means you move to the left 2 units.
Now, one thing I can't remember is if the number is OUTSIDE of the parentheses, do you reverse it? Of so, it will look like (x-1) - 3 means you move right 2 and up 3. If its not reversed, you would move down 3.

Also, one more thing: If there is a negative before the parentheses, the parabola goes downwards, not upwards. Feel free to correct anything wrong that I said, as I'm not even sure if I'm right.

Yes this. We just went over this in pre-calc.

Horizontal
(x+2)= transform left 2
(x-2)= transform right 2
Vertical
(x)+2= transform up 2
(x)-2= transform down 2

The parenthesis (or the lack thereof) matter greatly. Left and right transformation is the only one where the given +/- are reversed. If the x and a value are encased in parenthesis, count on it being horizontal transformation. If there is no parenthesis, or there is a value outside the parenthesis, it is vertical. For example in a parabolic graph:

f(x)=(x+2)²-5

The graph would shift left two, and down five.

f(x)= x²+5

The graph would shift up five.

[Flush535]

f(x) = (x+2)  -- two to the left horizontally. anything inside the parenthesis is inverse. this is affecting the x's
f(x) = x + 2  -- it's outside the parenthesis, so this moves it up two. this is affecting the y's

after 3 tutorial videos i know how to do this stuff, also thanks everyone for helping me <3

quick someone post a linear formation thing and ill try to solve it!!

[Flush535]

f(x) = -(x + 3) - 5

[sorrel]

f(x) = -(x + 3) - 5

g(x) = -x-8

right?

[Electro]

OT: |x + 6| = -7

solve it or die
