Which coordinates notation rules are for reflections?
ludmilkaskok [199]

Answer:

To write a rule for this reflection you would write: rx−axis(x,y) → (x,−y). Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1

How to graph transformations of quadratic functions
miskamm [114]

Answer:

Shift "h" units to the right, "k" units up, and reflect over the x or y axis when needed.

Step-by-step explanation:

1) I want to talk about reflections first.

  • Reflections across the x-axis --> y = ax^2, a is the coefficient. if a is negative, then the equation should be reflected across the x-axis. This is known as a vertical reflection.
  • Reflections across the y-axis --> y=a(bx)^2, b is the coefficient. If b is negative, then reflect the equation over the y-axis. There are cases where the reflection across the y-axis does not change anything. But, let's say its y=(x-3)^2... the reflection across the y-axis is different (that equation is: y=(-x-3)^2 )

2) Rigid transformations

  • Horizontal transformations (to the left or right): y=a(bx-h)^2, factor out b from "bx-h" and whatever h equals is the units to the right. If h is a negative number, then you move to the left.
  • Vertical transformations (up and down): y = a(bx-h)^2+k... k is just the units up... if k is negative then we move it down.

Example (check image for visual)

We transform y = x^2 to y = -(-x-3)^2+3 , you move right 3, then reflect across the x-axis, then reflect across y-axis, then move 3 up.

--------------------------------------------------------------------------------------------------------------

Note: In the image, the red line is the original function, the blue one is the transformed function. See if you can follow along with the verbal instructions I gave above.
